Adapted from freeformz's Bambu Labs PETG Glue Holder, I added 2 SKADIS pegs on the back for stable hanging. 

I believe I used a modified version of pegs from Rod's IKEA Skadis Fusion 360 Models for the pegs. 

This model has a peg clearance of about 4.5mm, so it's a pretty snug fit on some boards. But that's good because the original design holds onto the glue stick pretty tightly, so you need the holder to really be stuck on there so it doesn't come out when you use your glue!
