Customizable Cross Dowel / Barrel Nut

thingiverse

Customizable Barrel Nut I need one for a [barn door tracker](https://en.wikipedia.org/wiki/Barn_door_tracker) and didn't find one in any hardware stores near me. Buying some online was silly expensive and shipping was almost the same cost of the nuts (bringing it close to $30!). It has to hold a couple of pounds only (camera + small piece of wood) so a print should do nicely. This will require post-processing to smooth if you need it to turn smoothly. I need this, but I'm not a stranger to sanding printed things. Sanding usually turns out very nice, especially when printed with higher resolution (lower layer height). FWIW, probably the simplest model I've ever made. I hope it works for my project! Included STL for a 50mm long barrel nut for a 1/4" bolt.
