It's well known that nylon based 3D printer filaments need to be dried out before they're used. What happens though when you have a 30+ hour print? The spool can take on a lot of moisture in that amount of time and compromise the print.
Many people have solved this problem by making filament dryboxes, somewhat airtight containers that contain a desiccant to dry out the air inside of the chamber.
I have to print several large parts from nylon for client, and I was having trouble in the last hours of the print due to the spool taking on water from the air. I decided to build one of these chambers but with a twist.
Mine is wall mounted! Space in my lab is a premium and the walls are free real estate.
The bolts are M3x10mm, and the nuts are M3 nuts, both from McMaster Carr.
