Each kit includes easy-to-follow assembly instructions in a graphic novel that features the Tinkineer characters. The comic introduces a physics concept or engineering mechanism that is the focal point of the model, all in a fun and engaging way! The result is an awesome kinetic sculpture and some new physics and engineering insight! Building requires only household white glue…no special tools! It’s a unique and playful learning experience for beginner and experienced Makers alike! Review: Outstanding! But two quick tips for assembly... - Before I forget, if you end up purchasing this kit - you may want to note the two items that I mention below. TWO QUICK CLARIFICATIONS REGARDING THE INSTRUCTIONS 1. On the bottom of page 17 in the instruction book they neglect to tell you that PART 19 should be sloping slightly to the left (rather than perfectly level). I didn't realize at that particular point in the construction, but this is the chute that feeds marbles into the pinwheel-shaped rotating piece that in turn feeds marbles into the largest gear. Little did I know that the "marbles" (actually more like ball bearings) would CONSTANTLY stall there unless PART 19 sloped to the left. So I ended up squeezing a 1/2 round needle file in there and I filed and filed until there was finally a slope. 2. Page 19, installing PART 30 - in the middle of the paragraph of text they mention that this is press-fit, and not to be glued. Everywhere else in the illustrations they include an image of a bottle of glue with a line through it to remind you if parts are NOT to be glued, but they missed it in this particular illustration, and I ended up gluing the part in by mistake. Luckily, everything functioned as it should have and so I didn't need to remove the piece. OK, now for a quick review. I am really very impressed with this kit. The laser cut pieces are very well done, easy to pop out of the plywood sheets, and fit together well. There is a tiny bit of play when connecting most pieces, but this is desirable because it means that there is room for the glue, rather than a force-fit that may scrape off the vast majority of the adhesive. As I was assembling (and certainly once it was up and running) I couldn't help but marvel at the level of though, engineering and cleverness that went into this design. Very few things manage to impress me on an intellectual level AND excite my inner child at the same time. The Dragon Coaster kit did both, and I was delighted. Lastly, here are some things I found useful as I assembled the project. They were nice to have, but by no means absolutely necessary: 1. Bamboo Skewers. I used these instead of the toothpicks provided in the kit to apply the glue. The blunt ends of the skewers also came in handy for popping the smaller pieces free from the plywood sheets. I think I got mine from a dollar store, but here's an example of them here on desertcart Bamboo BBQ Skewers, 100ct 2. Condiment Cups. I use these all the time to mix small batches of epoxy, or to hold paint. In this project, I poured small amount of glue into the cups, and then would dip the tips of the skewers in to get glue for assembly. Crystalware, Disposable 2oz. Plastic Portion Cups with Lids, Condiment Cup, Jello Shot, Soufflé Portion, Sampling Cup, 100 Sets - Black Cups with Clear Lids 3. Needle Files. I used the round file to remove the tiny burrs inside the teeth of the gears left over from where they had been attached to the main plywood sheets. I also ended up using the half-round file to fix an assembly mistake that I made. These are probably the least necessary, but I was happy that I had the set. Needle File Set (HIGHEST QUALITY 6 PIECE SET) Hardened Alloy Strength Steel - Mini Needle File Set Includes Flat, Flat Warding, Square, Triangular, Round, and Half-Round File. 4. Wooden dowel with a disk magnet glued to one end. A quarter inch dowel fits nicely (9/32 inch might be a more precise fit) into the holes built into the base. I cut one to about 4 inches in length and glued a quarter inch diameter neodymium magnet to one end. This comes in handy ALL the time. If a marbles falls off of a track for whatever reason, they seem to have a distressing tendency to hide under parts that I can't get my fat fingers into, lol. The magnet on a stick grabs them from out of wherever they may try to hide. The non-magnetic end of the stick can be used to nudge a ball back into motion. I highly recommend this kit! Review: Great fun to make - Great fun to make. Found only a few parts somewhat difficult to fit and did a small amount of trimming on just one. Extremely well engineered and designed kit, although I really don't think it would be good for anyone that didn't have a fair amount of modeling experience. I used 5 min. epoxy instead of white glue. Could have used carpenter's glue, but wanted faster curing time. Did have to split each day's worth of work and mix small amounts of it frequently, but I could go back to work after an hour if I wanted. A GREAT help are these: https://smile.desertcart.com/Tooltron-00015-Micro-Applicator-Brushes/dp/B004KYYOH2/ref=sr_1_9?ie=UTF8&qid=1523185692&sr=8-9&keywords=microbrush They let you get glue onto joints after you've put pieces in place as well as only put glue where you want it and in just the right amount. There are other versions of these, but most can't be bent in angles to get into tight spots. One BIG issue I have with Tinkineer is their using grey fonts for the instructions yet going all out for the cartoon preface. WHY???? ## Features - Build your own working roller coaster model made of real wood! The Dragon Coaster is full of dips and turns with some engineering and physics thrown--so once you build your coaster, you can run marbles through it! - The assembly instructions feature a graphic novel with the Tinkineer cast of characters--Kelvin, Joule, Newt and friends--to communicate meaningful STEM concepts in an engaging format. - It's a fun way to learn about roller coaster design and conservation of energy while making an awesome kinetic sculpture! - The Dragon Coaster takes approximately three to five hours to build, and measures 8" when finished; for ages 12 and up. Made in the USA. - It also connects with the Skate Park (sold separately), so you can expand your marble empire and shuttle marbles back and forth! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01NC3LB06 | | Age Range Description | 144 months to 1188 months | | Best Sellers Rank | #401,663 in Kitchen & Dining ( See Top 100 in Kitchen & Dining ) #4,840 in Bar Coasters | | Brand Name | PlayMonster | | Customer Reviews | 4.4 out of 5 stars 408 Reviews | | Educational Objective | STEM | | Global Trade Identification Number | 00857479006022 | | Included Components | Laser-cut Birch Wood Parts, Metal Axles, Marbles, Tinkineer Graphic Novel with Assembly Instructions | | Item Dimensions | 2.75 x 11.25 x 11 inches | | Item Type Name | Stem | | Manufacturer | PlayMonster LLC | | Manufacturer Maximum Age (MONTHS) | 1080.0 | | Manufacturer Minimum Age (MONTHS) | 144.0 | | Manufacturer Part Number | MADC100BB | | Manufacturer Warranty Description | No Warranty | | Material Type | Wood | | Model Number | MADC100BB | | Set Name | Marbleocity | | Size | 8 inches | | Theme | Building | | UPC | 857479006022 | | Unit Count | 1.0 Count | ## Images ![Marbleocity Dragon Coaster - Image 1](https://m.media-amazon.com/images/I/61RON-z2XtL.jpg) ![Marbleocity Dragon Coaster - Image 2](https://m.media-amazon.com/images/I/712PIv8hjAL.jpg) ![Marbleocity Dragon Coaster - Image 3](https://m.media-amazon.com/images/I/71NU0fCzX4L.jpg) ![Marbleocity Dragon Coaster - Image 4](https://m.media-amazon.com/images/I/61WWYrVroaL.jpg) ![Marbleocity Dragon Coaster - Image 5](https://m.media-amazon.com/images/I/71wMpsmLiIL.jpg) ## Questions & Answers **Q: Does the motor from the video come with the kit? If not, do you know if they sell that additionally?** A: No it doesn't come in the box but I just say a new advertisement showing they are now selling the motor kit separately. **Q: Can I use any type of marble?** A: These kits come with 8 chrome steel ball marbles but you can buy more - amazon has them, just be sure to get the correct size 11mm or 3/8". **Q: How fragile is this? Would like to build at one location and transport to another.** A: It's sturdy, but it's clearly man-made. It's movable from one room to another. I wouldn't load it into a crate with other toys and expect it to survive all in one piece for long. **Q: If i've already assembled the skate park, can i get this and get them to work together?** A: Yes. You can actually make them work together and then switch to working independently. In fact (if you're REALLY fast) you can do it WHILE they're running. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Outstanding!

WHY???? ### ⭐⭐⭐⭐⭐ Very satisfying payoff. *by A***E on July 15, 2020* Put this together with very engineering-minded 7yo and it was super-enjoyable! Easy to follow directions (though I don't understand why after a few steps, they decided to stop highlighting in the illustrations where glue should go - they were just like "OK, we've shown you a few times so now we're not showing you anymore, you figure it out," and it doesn't seem like it would have been that much more effort for them to keep doing that). Works really smoothly and looks great. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/44821319-marbleocity-dragon-coaster](https://www.desertcart.tn/products/44821319-marbleocity-dragon-coaster) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-08*
