Snapware 40 cup Dry Box

thingiverse

Want a dry-box that holds more than one filament spool and isn't a huge box? I do too! The main rod is designed so the spool sits on bearings for a smooth, non-jerky filament feed. The main rod has a separator guide in the middle to keep a single roll from rolling over. Some force or sanding may need to be applied to get the bearings onto the pole. It should fit tightly to keep the bearings from moving around. A "Bearing Helper" file is available to help you install the bearings on the rod. Place the bearing on top of the cone and tap the rod through the bearing into the helper, just like hammering a nail. The bearing should be about a finger's width on the rod. M3 screws are needed to secure the bracket to the container walls. If worried about air leaks around the screws, recommend using either O-rings or a dab of E6000 glue in the hole when inserting the screw. I recommend aligning the filament pass-through with the top or bottom of the filament roll. I placed mine in the middle and it causes the PTFE to rub against full rolls of filament. Being near the top or bottom will allow for smoother operation. <u><b>Non-printed parts</b></u> 4x 608 bearing Snapware 40 Cup (9.5L) container 4x M3 screw <u><b>Recommended extras</b></u> PTFE tube cap (not my design) https://www.thingiverse.com/thing:2459359 Filament passthrough (also not my design) http://www.thingiverse.com/thing:1750875 Edit 5/16/2020 STEP files uploaded.
