Magnet storage
This is a simple way to store all the little magnets in a Prusament box.
Fit in box
There is 203x205 mm version, this is a tight fit in the Prusament box and assumes you remove the side panels of the lid of the box.
The 202x202 mm version fits loosely in the Prusament box.
The bottom of the storage cylinders is rounded for easy retrieval.
Strong magnets will still attract each other so Flex TPU covers are provided. The covers also make storing the box easier.
Covers
There is a small and a big cover. I printed these in Flex TPU.
The state of the steel/satin sheet used to print the covers will be visibly reflected since the covers are printed upside down.
The picture below shows the big cover printed in three different ways:
On the left with glue on a steel sheet, the glue markings are clearly visible.
In the middle printed without glue on a steel sheet, then the state of the steel sheet is imprinted on the cover. And you may need pliers to detach the TPU from the sheet.
On the right is a dual filament print using the satin sheet. The bottom 0.35mm is printed in Prusament PETG, the rest is TPU. This cover is visibly much nicer and works as well as the others. It does require manually editing the gcode file to change the bed and nozzle temperature (gcode available for MK4).

FreeCAD
I created this yesterday using FreeCAD, the source is also available to you. I wish more people would share source files and not just .stl or .gcode.
