This paintball marker wall mount was designed with the intention of being both simple and easy to use. Simply print both pieces out of high-quality PLA, mount the wall mount to the wall using drywall anchors (use the screw holes in the mount as a guide to make marks for the placement of the anchors), screw the ASA adapter snugly into the marker, try to make one of the fins on the ASA adapter parallel with the marker's grip frame (don't worry if it is not perfect), and slide the ASA adapter into the wall mount.

Print Settings: 20% grid infill, 0.2mm layer height, no supports

Drywall Anchors (Any anchors with #6 screws should work): https://www.homedepot.com/p/E-Z-Ancor-Twist-N-Lock-50-lb-Self-Drilling-Drywall-Anchors-with-Screws-6-Pack-11353/100171703

Please note that I have never printed these out of a material other than PLA and there may be better print settings. I am not sure if the tolerances are compatible with the slight shrinkage of PETG or other materials.
