https://www.thingiverse.com/thing:2268473 is a fantastic Gladiator Geartrack Gearwall hook, the best I've found on Thingiverse and this remix does not try to improve it. Rather it adapts the solid connection to a different type of hanging need -- heavy cylindrical tools like a crowbar.
Pictured here in PETG, this is a very solid way to hang your heavy items.
The hole is 30MM (1.181 inches) which should fit your mid-size crow-bar or other heavy item. Measure the widest part of the pole which is often at the bottom in the pry area.
Mounts to the Gladiator Geartrack system.
