This was remixed to hold the 4cm cylinder paint bottles that my airbrush takes. Now I can get them off the desk. Requires some support structure for the bottom lip.30Sep2015: Updated it with a slightly wider opening and thinner bottom lip. The airbrush paint bottle was a little snug and the bottom lip just really didn't need to be as thick as it was.This model prints much better if it is oriented on it's side so. It will require less support material and the pegs will be much stronger.
