Wheels for a standard Kyosho Mini-Z axles. Diameter 20mm, offset +2,5/3,5/4,5mm Fits: Atomic DRZ/DRZ V2, WLToys K969/K989 etc.
No additional supports needed. There is already an inbuilt support to compensate for the particular offset as highlighted on the pictures - you will need to cut that off after the print.
In case on any inconvenience, please contact me and I will do my best to adjust the model.
