Drawer Filament Storage System

I know that I am not the only one with lot of filament sitting around in messy piles, and no long wall to put up a filament rack. but I did have a cupboard, so I designed a storage system that fits in a deep place and holds a lot of filament. This system uses drawer racks from amazon, (link below) and can fit in a place 228.6mm (9in) tall by 508mm (20in) long. My space was 18in tall, so I stacked 2 sliders one above the other. the body of the slider is made out of 1in dowel. The draw sliders need to be set a minimum of 8mm (0.35in) above the bottom of the cavity and the bottom of the each drawer slider in a stack needs to be 186mm (7.35in) above the top of the previous slider. And the top of the top drawer slider needs to be a minimum of 200mm (7.88in) between the top of the slider and the bottom of the top of the shelf.

For the length of the dowel. I would measure the width of the widess spool you have, add 2-5mm (I added 2mm) of clearance, and them multiply that entire number by the amount of spools you want to store. my rack 15 elegoo 1kg spools wide. The aria you need is 13.5mm of extra aria on both sides of the dowel for the width of the sliders plus a bit of wiggle room. There is holes for the dowel to be screwed into the printed rack, but I did not screw mine in because if your sliders are not perfectly parallel this will allow the slider to expand and contract a but to compensate. The sliders can hold 45 kg max, so that is 22kg wide. I printed all 3 parts for one side at a time. I printed them out of PETG and with a 0.6mm nozzle and 0.3mm layer height. I used 6 walls and 15% infill, (except I used 30% infill for the narrow arias).

My entire rack used around 1600g of filament. And cost a total of around $90.00 CAD to build.

Note: there is a difference between the right side and the Left side racks, due to the hols for the screw holes for screwing the printed parts to the drawer slider. Drawer slider. https://a.co/d/05wFnKSY
