Wall mounted holder/hanger for your paintball markers.
Wall mounted screws are hidden behind the pegs for looks.
I printed in PETG using 6 walls for strength and to reduce the chance of delamination in the portion that the pegs are slotted into.
Depending on your print settings and geometric tolerances you may need to reduce the size of the pegs to 99% or 98% for them to slot into the mount perfectly.
