Sterilite 20qt Filament Dry Box v2

thingiverse

Compared to my initial attempt, this is a far more user-friendly filament dry box system using Sterilite 20qt storage boxes. No longer must I remove all spools just to replace one. For the filament caps, see my previous version here: https://www.thingiverse.com/thing:2849767 All parts print without supports in the provided orientation. EDIT: After revisiting, I tweaked the sizing of the spool rollers and rod holders to accommodate up to 75mm wide spools in all four spots. Print sixteen halves for a full set (Previous_Version.zip contains old STL and STEP files). Print eight of each size spool roller halves then glue them together to create 70mm and 75mm rollers. These sizes strike the best balance I could achieve, given the width of spools used and available space in the 20qt container. The 75mm width fits my Atomic spools, while the 70mm width accommodates almost everything else. The only spool requiring spanning across two rollers would be an original Prusa spool that came with my MK3. Install regular 608 bearings into the ends of the spool rollers. Almost all bearings I have here slid onto linear rods without issue, but a couple were too tight of a fit; your mileage may vary. Use 330mm 8mm diameter linear rods for spool roller supports. These are identical in size to Prusa MK3 Y rods and also available on Amazon as a standard size. Utilize the drill template to mark rod holder holes and drill out with a 3mm drill bit. Install with T parts facing upwards, securing with M3x12mm screws and M3 locknuts. Assemble all parts onto linear rods before securing them in the box.
