About
This is a silica gel box for about 100 g of silica gel. The silica gel you use should be 2 mm in diameter or larger. The box has a lid that slides in place and it is secured with a single M3 head cap bolt (6 to 12 mm bolts will fit).
I keep one of these in each of my dry boxes that hold about 8 spools of filament, it keeps the humidity down and the prints are improved. The silica gel box is quite sturdy with 3 mm walls and could be made a little thinner if you want to save some filament, I will upload the step files so you can edit the design easliy. A complete (empty) box with lid is around 80 g.
Threaded or heated insert?
I've uploaded two versions: One version is designed for a threaded M3 insert, I use the Trianglelab inserts linked below under BOM myself.
The other version is threaded where you just need to screw in an M3 bolt, it's natually not as strong but is fine as long as you don't overtighten it.
BOM - Bill of Materials
You need some head cap allen bolts and some brass inserts. I use these:
M3 Hex Head Cap Allen Bolt (6 to 12 mm will fit)
Trianglelab M3 Brass Embedded Nut
You can also find some silica gel on AliExpress, I'm using some that are 2 to 3 mm in diameter, just search there and you will find some suitable gel.
