Guardian Peg Hook Adapter

Do you have those Guardian wall rails and don't want to spend a fortune on those specialized hooks?

Then try this print. It should print in about 25 minutes a piece at 30% infill with no supports

1] Buy some 2" or 4" metal peg hooks for 1/8 to 1/4" Pegboard (about $0.25/piece)
2] Slip peg hook into printed part
3] Slide into wall mounted rails

I don't know the weight rating, but they are certainly working in my garage to hold plenty of things
