Filament dry box for 3-4 spools of filament by bummster

Last crawled date: 4 years ago

My dry box for 3 - 4 spools of filament. There are many dry box plans out there. This one is mine.
The rod is at a good height for most spools when using a pair of spool hubs on each spool
1 Sterlite 20qt air tight box.
24 3mmx10mm machine screws (3mm x 8mm will work but I like a little bit of thread sticking out of my nylocks)
24 3mm nylock nuts
24 3mm washers
1ft 3mm OD x 2mm ID PTFE tube.
1 12in 5/16 threaded rod
I used 3mm OD x 2mm ID PTFE tube because its what I had on hand.
The nut reliefs are too shallow (1mm) on all parts, but they worked for me.
The round base of the rod holder and the U shaped 'extrusion' are perpendicular to each other. The Sterlite box has an angle of like 3 degrees or so on all sides. It's not a big deal.
Loaded several versions of the U shaped rod holder.
m3 with reliefs (m4 hole w/ m3 nut relief. This one also has an itty bitty section to center the rod. It makes it special.)
m3 with reliefs dry-ish edition (Same as above but with some added flavor. It makes it extra special. And I couldn't get it to print very well either. .2mm deep relief text on the back.)
8-32 with reliefs (m5 hole w/ 8-32 nut relief)
m5 hole with no reliefs
For a size reference, the red filament is Hatchbox PLA, the one in the middle is EasyFil PLA, and the one on the right is Makergeeks ABS.
I haven't had the rod holder pullout of the sterlite box walls using m3 washers, but if they do I'll post a backing plate.
