Water bottle weight adapter

thingiverse

I was struggling to find any affordable small weights to put on my barbell to work on increasing my bench press. After looking around for 3D printed weights, I decided to work with what I had lying around, and designed this clip for a 1.5L water bottle (athough it would probably fit other sizes). The ring is designed to slide on a 2" barbell. If I had more patience, I might have made the ring width thicker so it doesn't interfere with the other plates, but it works for my purposes. The entry of the clip is /just/ smaller than the hole, so it holds the bottle in place when it's seated in the holder. Just press it and it should pop in. The pics show the fact I used a 0.3 layer height, as I'm all about function over form, so it doesn't look pretty, but hey it works! Took about 2.5 hours to print one. Obviously, you could fill it with sand or gravel (or feathers if you like - I'm not judging) if you wanted to change the weight, but disclaimer: I've only tested the clip at 1.25kg.
