OpenRc f1 front rim & axle for 12x18x4 bearings

Instead of sourcing 2 different bearing sizes for the OpenRc f1 project I rebuilt the front rims to use the same size bearings as the rear axle. The bearings on amazon are sold in a pack of ten. I doubt I'll be blowing up bearings that fast.

The rim also includes a new front axle, a bushing adapter if you already have the axles printed and a new lock nut.
