Dry Box System

This is a dry box filament feeding system of my own design. The only thing you need to have is some kind of plastic storage box, some kind of sealant for the lid (if it isn't airtight already) and a rod (aluminum, plastic, metal tubing) of max 24 mm diameter (if you don't scale the model up).

The idea was to be free of having to use any metal screws and nuts, so you don't have to deal with precisely drilling the holes for them.

I used a double setup, because the KIS box is large enough, but one can use as many racks as they want.

For one rack you will need to print two holders, two holder nuts and as many feeders and feeder nuts as the number of filament spools you will have on the rack.

The feeders are M8, so they need an 8mm hole in the box to be set in. The feeding hole is 2.5 mm, enough clearance for 1.75 mm filament. If you feel there is not enough clearance, drill through with a 3 mm drill,.

The holders are M24, so they will need a 24 mm hole in the box to be set
