I used Simplify 3D to slice this object.
For this project you optionally need 4x 12x2mm neodymium magnets. These magnets assist in holding the inserts in the cartridge container and from falling out once opened. Simply use CA glue to glue the magnets into the cartridge holders.
Print the Cartridge inserts horizontally and the Holder Vertically. No supports are required if printing in this manner.
The magnet at the bottom of the cartridge enclosure is tricky to apply, but can be done easily if forethought applied.
Simply hold the enclosure upside down (logo side down), apply glue to the proper side of the magnet then slide magnet into the enclosure (with glue facing up) then slide a cartridge insert into the enclosure into slot #2 (the bottom slot, upper if upside down) to pull the glue applied magnet into its desired hole. Allow to rest for a few minutes while the glue sets. If this fails just use a little CA glue solvent and try again.
The bottom of the cartridge enclosure is wide open for you to add your own initials or custom message as you see fit.
I hope you all enjoy this as much as I have.

If using Simplify 3D, under print settings go to Advanced > Movement Behaviour > Avoid crossing outline for travel movements > Maximum allowed detour factor = 7.0. This is important to prevent cobwebs from forming inside of your slots. I'm unsure of the equivalent setting in Cura or other slicers.
If printed using the detour factor, no post print polishing is required.
