For mounting 4 Mason jars to your peg board.
I couldn't print the whole thing on my bed so I've included the model split in half (both the LH and RH for those who don't know how to mirror) as well as the full model.
I glued it together using cyanoacrylate or super glue and a couple of binder clips to hold it together while it set.(Image 3)
For 1/4" or 6.25mm peg holes.
