Great wheel to add more detail to your scale auto and diorama! Will fit a 2.5mm axle. If you need an specific axle size hole and don't know how to do it, just let me know, message me and I'll help you. If you wan't, you can rescale it too. I recomend you print one unit just to make sure is the right size for you. There's no gap between the wheel and the tire, if you need, scale up 2~3% of the tire, so it will fit better to the wheel. Do a test print before printing the full set. If you like my designs, you can tip me and credit me with the design. If you like to sell the prints of my designs just buy them here and credit me with the design, no need to ask or pay commisions. Just scale it up to the size you want and print with you favorite resin printer. If you need any help, don't hesitate on contacting me. Drilling and Sanding may be needed.
