Varia RCT715 mount

This is a mount for the Garmin Varia RCT715 bicycle rear camera, light, and radar.

It is still a bit rough around the edges- read: this is only my second iteration, and haven't really used it either- and the dimensions are not very precise, but probably still more precise than my printer. Unlike my Retro Varia camera cleat, this does not require any disassembly of the varia. However, I still strongly recommend attaching some kind of tether to the varia in case the mount fails.

Print one each of the twist lock, cleat holder and, optionally, post mount. Print three of the standoffs. Supports are not necessary. Also needed are three M3 screws at least 12mm long to hold all the parts together and two zip ties to attach the mount to a seatpost. Optionally, the mount can be bolted to other bike attachment points besides the seatpost mount.

To assemble, the cleat holder slides into the twist lock, three M3 bollts go into through the holes in the cleat holder and twist lock, the standoffs then fit over the bolt ends, and the bolts then get screwed into any flat surface with M3 threaded holes with 8mm centers such as the included post mount.

Clearances may be a bit tight, my printer leaves big blobs, especially at seams, so I had to shave them off with hobby knife. The standoffs are part of the locking mechanism, so if the twist lock doesn't snap into place, or is too hard to close, then resize the standoffs either larger or smaller in outside diameter, respectively.
