Glueable Stopper
Description
Can be attached to a spar and glued in place through the small hole in the side. This is an alternative solution to C-clips, and I've found these stoppers to stay in place much better.
I still use c-clips for prototyping because c-clips are easier to remove and possible reuse. But for most builds, I prefer these stoppers.
Resources:
For the best experience, use the online Fusion 360 Project. The project includes parameters to adjust hole sizes and tolerances.
The Project is also available as a .f3d file here: Glueable Stopper v14.f3d

Printing Notes
I print these with Sainsmart 95A TPU, no supports, and 100% infill.
