Filament Storage Dry Box

A simple filament storage box.

I got my box at OBI, a german hardware store.
The top is sealed with a rubber seal for windows, while the box contains dry pearls to reduce the humidity (mine settles at arround 25%).

You'll need:

- 8x M4x12 screws and nuts for the drainpipe holder
- 4x M3x8 screws and nuts for each filament feeder
- pneumatic fittings for PTFE bowdentube (M6 or M10)
- a piece of PTFE tube for the feeders
- HT drainpipe 50mm diag (mine is about 47cm long)
- dry pearls (e.g. ST-Trockenperlen by Steiner Chemie; ~15€/kg)
- big plastic container with lockable top (e.g. Cadiz XL by OBI)
- window rubber seal with double-sided tape

You can also use longer screws for each part.
