Wall / Cupboard / Desk Infinite Length Simple Spool Rack

thingiverse

Hi all, I never have space for anything, especially spools of filament, so had the idea of hiding the unused rolls at the back of my desks .....sitting place....leg hole.....? It could of course be used in a cupboard, bookshelves and at a push in between walls. Simple set of left and right brackets to hold 20mm plastic electrical conduit (they sell it in <a href="https://www.diy.com/departments/mk-white-heavy-duty-conduit-dia-20mm-l-2m/109150_BQ.prd">BnQ</a> or you could use metal) and a centre piece to take up some of the strain between the two, each need 4 screws. To help with installation each bracket has a square back which can butt up to the surface behind it, the flimsy looking strap between the brackets is just strong enough to hold the other part in place while you screw them to your chosen surface,so you only have to measure up once per side, but adds hardly any extra time to the print. When measuring up for your own rack, mine is 600mm, I have one centre support piece @ 300mm, but I think 200mm centres would be better, minimum clearance from above is also 200mm, this is measured from the top surface to the top right angle corner of the bracket, this allowed me to get a ProtoPasta spool (the tallest I have) in and out smoothly. Probably best printed in ABS or PETG for long term strength, I used PLA and its has held up fine so far, but I have nothing beneath them to worry about if it fails :) Also remember to test the racks weight holding ability before you use it, the weak point is most likely to be fixings on the middle supports as there is a lot of shear force on quite small screws in quite weak material (chipboard).
