fuel cup rubber band for BMW

thingiverse

This DIY rubber band substitute never lives up to its promise of lasting long. Printed from cheap no-name TPU on an Ender 3, it's a straightforward job for the first part but requires some fine-tuning for the second. I've found that printing it upside down with a Brim and slowing down the print speeds yields the best results. As designed, both pieces snap together seamlessly using the same 1.75mm TPU filament. For BMW E82 owners.
