This is designed to hold an aerosol can, canned air, etc. on your multiboard. It is attached via the overly strong pegboard clips and holds the cans at an angle. Two different models are provided, one with built-in support and one without if you'd like to add your own. It should be printed on the side to provide the most strength for the pegboard clips. The model is not oriented this way. The pre-supported model may have the slightest of sagging at the top of the cylinder but will print successfully on a Creality K1. To remove the supports around the pegs, use your side cutters to gently separate the supports from the pegs. It requires three horizontal pegboard spaces to clip in and is designed so you can butt them up horizontally to store multiple cans with no gaps in between (see pictures). Correct vertical spacing will have three open peg board holes between two of these holders. There is a small triangular hole in the model for any spray nozzles your can's may have.
