Needed a glue gun holder to be Gridfinity so I remixed rxstud1983's and added a 3x3 grid. There is a slot for a drip tray and somewhere to put gluesticks but I use it to hold the power cable.

I would print using PETG or ABS as it needs to be able to widthstand the temperature if you put it on while it's still hot.

Glue gun I use is the Assark Hot Glue Gun, which you can get here: https://amzn.to/3TY0fy8
