Made to connect a broom to hold up a lightweight board as a paint shield. Internal Diameter is 28.5mm. Broom handle was 28mm. I wanted it to be easy to slide on and off with just enough “grip” to keep it from spinning in the air. If it's too loose, a wrap or two of black tape will snug to your liking:)

Hopefully someone may also have a use for it. I'm sure there are a ton of other applications like a “groovy” closet rod mount?

If you are not comfortable with changing the diameter to fit your needs, just ask and I'll post the size you'd like.

Note there are two models, I made the primary one pictured with the holes and it is super strong and saved an hour of print time as opposed to printing the second solid model.

25% infill was more than needed but works great. Excited to see posts of other uses.
