I designed some fork-mount pieces so that I can mount my bikes inside my car for longer car rides. This has 2 files - a 15mm thru-axle mount, and a file for a 15mm thru-axle adapter for a normal 5mm quick release. The idea is that you can mount either a mountain bike with a 15mm thru-axle, or you can use the adapter pieces and mount any bike with a normal quick release and 9mm dropouts.
I suggest printing the adapter pieces with 100% infill as they will be compressed by a quick release and a bike fork will be mounted to it.
Because the inside of the adapter pieces is really tight, I suggest using a drill to clean out the support pieces. I printed with supports at 8% thickness and that seemed to work really well.
