Pin to replace bolts in spray can harness
3d printed pins to replace the bolts and create more stable connections between the parts of the spray can holder - and also save like $8 in hardware
They have a hole in the end if you want to put a cotter-pin type thing in there (wire, toothpick, whatever) but honestly they fit tight enough that you can just push them in and call it a day :)
Not recommended for the two bolts that tighten the brackets around the can, use real bolts for that, or a ziptie.
UPDATE: pins only seem to fit the brackets and pole socket holes, the top two pieces seem to have slightly smaller holes. I'll see if I can add a couple slightly slimmer pins for those.
