These are very well designed and print perfectly on a well setup printer. I used PLA Silk and PLA+ with no issues. These were printed on a Ender 5 Pro and Sidewinder X1 and assembly was great. I now own all of the offerings from Luka. Thank you and the kids thank you!
I loved printing this and sharing the process with my kids. It’s a great tool to teach debugging, fixing, and testing. Only problem is now we want to print them all! For folks considering PETG vs PLA, PLA works better. I had some figment trouble with PETG but made it work. I reprinted in PLA and everything turned out much better. YMMV
I have just printed one with all accessories. Everything works fine and looks great!!! Thanks to the designer for an awesome job!
Great model to show people in a playful way what 3D printing is capable of. Prints well, assembles well and supported well by the author.
I loved the modular concept and promptly purchased the Two Wheeler and three modules. The price was fair and I'll be buying more in the future, and recommending it to other 3D print hobbyists.
The Test Print was too tight with PrusaSlicer, but perfect on my CR10s Pro with Simplify3D so that's the way I went.
I've enjoyed printing it and assembling it and playing with it, but it's been a challenge. I found that throughout the model, tolerances were too tight. The printed pins fit neither the wheels nor the supports; rather than sand the pins down that much, I simply drilled out the holes. Likewise, the M3 bolts and nuts and the FlipFlop didn't fit; I had to drill out every hole. I cracked two parts while forcing the nuts into their spots and wound up melting the rest in with my soldering iron. The Split didn't work and had to be reshaped. Several parts were too tight for 1/4" ball bearings and would be impassible for the 9/32" bearings in the hardware kit. They took a lot of work to reshape.
I'd guess that this was something about my printer, but my previous project, Thing #4002445 fit together beautifully (with the exception of the axles). Why should this one be so much different? I plan to redo some parts using PrusaSlicer to see if that makes a difference.
Overall, this design is a work in progress that will continue to improve. I consider it well worth the price and the effort of printing and assembly.
