I'm tired of cutting and replacing zip-ties for the canopy every time I need to work on the electronics under the canopy of my Tiny Trainer v1. This integrated bumper/tie-down kills 2 birds with 1 stone.

Printed with TPU at 0.2mm layer height, 2 walls, 100% infill. Enable overhang setting at reduced speed.
