I created this using Onshape.com. You will need to print 4 tires, obviously. I included the original tire file and a larger 26mm tire for racing. The 26mm tires don't fit on the front. I may fix that in the future. You may notice the white cover in the photos is different. It was my original lid design, but didn't stay on during the high speed tests so I scrapped it. I also have one up on blocks because we all know someone like that. In some seriousness, though, I didn't make it to race around, the pegs holding the wheels on are not beefy enough and will break. It took a bit to figure out the heart hub caps. It is a box with a lid that could be suitable for holding some candy or jewelry (ring pops). It will comfortably seat a small family of 20 or so gummi bears. Let me know if there are any problems or if I can improve it. (Besides the tire issue, I'm working on that.) I used both my Flashforge and my Ender 3 Max Neo and used PETG filament. I haven't tried it in resin yet, but if you do, let me know how it turns out!
Just a note; the tires are small and I would feel bad if someone were to choke on one. Please be careful. (but, then again, we are all printing out of plastic and generally take those precautions anyway.) Happy printing!
