Here is a system I created in order to float a ton of filament rolls over my printers to allow for easy swapping and management of materials. I designed this system because while I like the idea of mounting my filament rolls on my pegboard, the existing fully 3D printable brackets require the use of a ton of peg holes in order to have a strong enough hold. Even then, the plastic pegs struggle to hold up that much weight. By utilizing existing standard hardware, you can get great weight-bearing strength and only take up a space of 1x3 peg holes. And let's be honest; while you could just go buy some metal brackets off the shelf, this is a great excuse to make something for our workshop. :)

Specs:

The bracket arms hold a 3/4" PVC pipe far enough from the pegboard for all standard filament rolls to clear with a bit of space to spare. The pipe clamps act as filament spacers and keep filament rolls from shifting side-to-side as you unspool filament into your printer. They slide on and off with ease as you squeeze the outer ring and tighten down around the pipe when released. Finally, the routing rings can be used to route filament straight down from the rolls to avoid unraveling over the side as your printer draws filament.

Required Materials:

• Standard 5/8" pegboard j style hooks (Heavy duty hooks meant for 1/4" pegboard work best, reference below)

Instructions:

• Print the arm brackets with supports only at the rear of the slot. If you put supports any deeper, it will be nearly impossible to remove - trust your printer to bridge. :)
• Insert a hook into the back of the slot and slide it all the way up as snugly as you can
• Insert and press/tap in the locking pin to keep the hook from rotating once it's on the pegboard

Recommendations:

• For every 6 kg rolls or so, add another arm bracket. For example.. for 6 rolls you would need 2 brackets, and for 12 rolls you would need 3 brackets.
• I bought my peg board hooks at Menards. Reference: https://www.menards.com/main/tools-hardware/tool-storage/wall-mounted-storage/5-8-j-style-heavy-duty-peg-hook/p-1444421797263-c-12657.htm?tid=-6483361717164408109
• In case you don't have one near you, most sellers use the same manufacturers and the hooks should be nearly identical - you can order them off amazon or pick some up at your local hardware store
