Raised Varia Rack Mount

This is a remix of my Varia rack mount. The problem with the previous version is that the fender would occasionally hit it when I forget and pop the bike up on its back wheel or when I remove the rear wheel when fixing a flat and put the bike down upright instead of laying it on its side.

This mount just moves the Varia up 45mm so the fender hits the rack first. It also uses a Bar Fly Garmin mount adapter since that's what I had around. The Fusion 360 file can be modified to fit other Garmin adapters, most likely by suppressing the last two features/extrudes, and changing the PuckHoleSpan, PuckHoleDiamater and PuckNutWidth parameters because non-Bar Fly adapters probably have different hole spacing and use M3 flathead bolts instead of the M4 used by the Bar Fly. Probably PuckHoleSpan = 22, PuckHoleDiamater = 3.2 and PuckNutWidth = 5.5.

Additional parts needed:
