Mini 4WD Plastic Spacers

thingiverse

These are plastic spacers that you might use in creating roller setups on a Mini 4WD car. There's 1.5mm, 3mm, 6mm, 6.7mm, and a 12mm spacer, which are the same sizes as some of the packs you can buy from Tamiya. I'd just buy some from Tamiya, but they're hard to get here in the US, since Mini 4WD isn't huge here. Figured printed ones would be good enough for my own use, but I doubt they're legal in more official situations. Make sure to check the rules of where you race if you're racing for real.
