Camera dolly wheel mount for skateboard wheels

was looking to build a cheap camera dolly using one of the many skateboard wheel/PVC pipe based designs out there so I designed this mount instead of trying to use angle brackets or PVC. Supports wheels with 8mm axles. I used the following hardware:

m8 50mm hex bolts
m8 nuts

You could change bolt lengths and add spacers/washers between the wheel and mount to accommodate a wide range of pipe sizes (the photo shows with and without a washer). Just print 4 of these, bolt them onto an MDF or
