Fits snug in the mount!
i finished the system, i will take it for a test ride next week and update this page with pictures of the system mounted on a bike and running the software. I had a 3 minute test ride just to see if the bike could supply the 3.6 amps it would need and it worked fine, the usb GPS sensor allso worked pretty good. (edited)
Finished product. The slot at start-finish is there so I can put a small checkered flag in between
used standard pla settings from prusaslicer, but increased printing temp to 212C
