Ran into the twist-lock by Shurdle LLC and wanted a way to make a private wall in my office. his twist-lock stuff can be found here: https://www.shurdle.com/models/twist-lock-threaded-peg-board
I made these to be cemented with ca glue (superglue) (after roughing up both surfaces with some coarse sandpaper) to the back of the hueforges at their topmost edge to allow them to be mounted as close to each other on a wall of the boards without gaps (or many of them at least) and like how well it's been working for me.
I print them typically in pla or abs (whatever is loaded up at the time for the brackets tbh. But they have been working well for me. Hope you all find them as useful as I have
