MicroSD Card Case

Each of these 3D printed pucks can hold 18 Micro SD cards and makes them so much easier to keep track of.

I printed in red, orange and green colours for on set organisation of 'hot' cards to be offloaded and cards which are safe to format.

I took the below design from Thingiverse and customised the G-Code in Prusa Slicer

Modifications

Added fuzzy skin to the bottom half of the main part

This keeps it nice and grippy and also makes it easy to determine which side is the lid. We don't want to be opening this upside down with 18 cards inside...!

Ironing 

Smooths out the top surface of the main part for a nicer look

Filament/colour change 

Two tone colour effect, this is how I achieved the black caps on the top and bottom 1mm of the part.
