Filament Spool Wall Brackets

I designed these brackets to be used in combination with cheap 15 mm diameter metal 'central heating' tubes. I used one: 15 mm x 1,2 mm x 2m and cut it in half. I costed me less then € 5. Printed with PLA+ it's sturdy enough to hold at least 13 spools no problem as you can see on my pictures. The brackets are also rounded inwards so they won't obstruct any spools right above the backets.

You'll need a long screwdriver (or perhaps a very small one) to be able to screw in the top screw. I used a Philips head screwdriver with a 150 mm length, and that was barely enough.

Use at your own risk, I'm not responsible for any failures or damage. Mine are still holding strong after 8 weeks with 13 kg resting on 2 of them.
