Barbell Collar Insert

A TPU insert designed for generic barbell collars.

Basically, I have a set of generic, inexpensive barbell collars that work fine except they're too loose - every time I drop the bar the plates start to slide apart. I have a strong preference against spring clips, so I designed these to replace the rubber inserts that came with the collar.

Rather than try and figure out supports, this prints as half the insert, so you use two for each collar fitted back to back.

From what I can tell, most of the genreric collars I've seen around follow the first generation Rogue HG collar design, so these might well fit just about anything that looks similar. ymmv, of course.

Now, stop printing and go PR something already.
