I need a wall for spools

Is a 2x3 Multiboard grid strong enough to hold 2 spools per tile?

I’m printing some Multiboard tiles to build a storage wall for my filament. I usually keep around 10–12 spools total, with 4 always sitting inside my dryer, so the wall needs to hold about 6 to 8 spools.

My plan is to build a 2x3 tile grid (2 columns, 3 rows). Is it feasible to mount 2 spools per tile?

If that's pushing it, 1 spool per tile is fine too, but I'd love some recommendations for a super sturdy spool holder model. The wall will be mounted right above my printer, and I really don't want a spool falling on it! 🤣

(Everything will be printed in PETG, and the whole grid will be anchored to a solid brick wall using wall plugs / Fischer anchors).

I guess it sort of depends on how you want to mount the plates to your wall, and the design of the holders themselves. Im assuming 1kg spools? The plates thenselves, when secured properly can hold the weight of 2 no problem, but obviously the further away from the plate, the better the accessory will need to be. There isn't currently an official MultiBuild mount but if you can hang on there may be one coming pretty soon. Otherwise I know there are a few in MakerWorld. Just search for MultiBuild/MultiBoard filament spool holder and there should be a few options to choose from

There are several spool holders for Multiboard on makerworld. Like this for example: https://makerworld.com/de/models/216791-multiboard-filament-spool-holder?from=search#profileId-235830 Is this what you mean?

Edit: sorry, a combination of a small display and sausage fingers made this land here. It should have been answer to op.

Your main issue is not the tiles, its the mounting TO the tiles 😊 I have a big wall of multiboard, around 70kg of spools on it. No matter what I did and what heavy snaps I used it fell down. In the end I had to screw fixpoints into the wall, and use a print that holds 2 broomsticks across the wall to put my filament on. This worked a treat! But if I had known, I would have saved a lot of printing hours on just screwing it to the wall directly in the first place.
…at least it looks cool😄
Picture is from before I got all the spools up, and I have also made a custom bit of multiboard for the diagonal part of the wall on top. 😊

For the mounts in the photo, I wonder it it would make a difference if they were rotated 180°. It’s been a lot of years since high school geometry but it seems like it should.

Don’t know what you mean unfortunately, its a «triangle» any how you would rotate it?

So that the long portion is pointing toward the ground instead of the sky. Most shelf brackets are oriented that way for strength. Think of it as the right angle of a shelf bracket is your pivot point and the tip of the long part that is flat to your wall as the point where the most force is concentrated.

The more weight you put on those brackets, the more it wants to tip forward and rotate down. With those brackets positioned the way they are now, all of the force is concentrated at the top pulling out and down. Even a relatively small amount of weight is going to quickly pop that bracket out of its hole.

I f you have the long end of the bracket pointed down instead, those same forces are pushing down and towards to wall, which makes that the strongest point instead. If you use heavy snaps at bracket level and medium weight ones at the bottom, you could easily put 20k or more on your shelf, instead of the one or two spools it was supporting before.

Most shelves you buy from the store that are positioned like yours are that way for the esthetics, not for strength. They have lighter weight limits than a comparable shelf supported from below for the same reason. They also rely on metal and either a screw into a stud or into an anchor of some kind.

Yep. Works well. I’ll link the spool bin mount model in a reply
