Is there anywhere to get hold of some tyres from please?
My CEL Robox is less hackable than my previous Printrbot 3DP and I can’t get it to print the Ninjaflex I have…
Suggestions welcome,
thanks,
Pete

There is rims stl for tamiya f1 tires

If for the F1, I have an extra set of stock tires printed with Ninjaflex, feel free to reach out and make an offer. Thanks.

Thanks both. TinkerMake… can you post to UK? I guess the cost of postage would be a starting factor in any offer… interesting though
