StackRack

The StackRack is a interlocking modular rack for storing and transporting filament. It can used with the rack only for open storage or with the cover for dry storage. It has a handle on top for easy handling or to be used as a carry case for transportation. Regular 200mm spools will snap into place. There is now a 3 spools per rack version (which will fit the X1C, P1P, P1S and A1),  or a 4 spools per rack version that can be printed with the H2D and H2S (or other large printer). You can chose to print with or without a hole for a hygrometer.

To snap the lock in place i recommend using something flat and sturdy to help push with. I used a saucepan. Some lubrication could help as well. Remove supports on the base plate before snapping the lock in place. 

The base plate should be fastened to the rack with superglue for easier handling and better sealing.
