These are pegs to allow hanging items using keyholes hangers.

They screw in small threads such as the peg holes in the multiboard. Just align them with the keyholes by screwing or unscrewing them, you should be able to match all the spacing distances.

Using the same principle as the T-Bolts, they print flat without support so they are very sturdy. I print them with 100% infill.

They come in multiple sizes:

• 3mm diameter & 3mm length shaft / 7mm diameter button
• 3mm diameter & 6mm length shaft / 7mm diameter button

I can generate more sizes (just ask), but these where the sizes I needed to hang a phone and a switch on my multiboard.
