These 4 parts are designed to mount a silica gel bag under the lid of an IKEA Samla box.

I hadn't seen anyone do something like this before, so I had to make a new system to attach the silica gel bag on top of the filament spools.

The parts with 'Mid' in their name are made to be mounted in the middle of the lid and the other pieces are made for the side of the lid (because the lid isn't flat).

You'll need 8 M4 nuts and 8 M4 bolts. You'll also need a rectangular piece of aluminum or rigid plastic to hold the bag.

Here's a video about a dry box where this mount is utilized: https://www.youtube.com/watch?v=fUOdMoCvSVo
