Multiboard Filament Spool Rack

Brackets to use with your Multiboard tiles and wooden dowels/closet rods to store filament spools.

The brackets are designed to fit 1.25" wooden dowels/closet rods that can be found at your local hardware store. I've also included various metric versions as well. Let me know if anyone needs to a different diameter and I will post additional print profiles that fit your needs.

A note on sizing:  I've found that not all closet dowels are made the same.  I have built-in tolerances in the design, but sometimes it's not quite enough.  You can adjust the “X-Y hole compensation” setting in Bambu Studio to give yourself some extra room.  I have found that adding +1.0mm, you can fit a 1&3/8" closet rod in the 1.25" model.

Mounting to your Multiboard
Required Multiboard Parts:

• (1) Heavy Weight-Bearing Hook Snaps (I HIGHLY suggest printing these in PETG)
• (1) Small Thread - Lite Multipoint (I HIGHLY suggest printing these in PETG)

Optional - depending on your setup:

• (1) 13 mm Big Thread, Flat Head, Push-Fit Hole, Bolt (if you are using 8mm offset mounts)

Place the Heavy Weight-Bearing Hook Snaps onto the peg on the top bracket and secure using the Small Thread - Lite Multipoint, like the picture below.

For the bottom peg, I used these 13 mm Big Thread, Flat Head, Push-Fit Hole, Bolts screwed into the Multiboard, use a spare push peg to help screw it in, if needed.  When screwed in all the way, the bottom of the bolt sits flush against the wall if you are using the 8mm offset mounts, helping to support the bottom of the bracket.  You may also use any other open snap you might already have on your Multiboard setup.

Depending on how many spools you intend to hang from this rack, you may want to reinforce your Multiboard tiles around the brackets with additional wall-mount snaps.  This will reduce the amount of flex on the Multiboard tiles to avoid any potential failures of the system.

Brackets can be printed using standard Multiboard print settings: 0.4mm nozzle, 0.2mm layers, 15% infill, random seams for strength. Supports are recommended for the push-fit pegs, but not required.
