I designed this as a basic parametric parts holder for when I am doing tasks, from holding pen blanks, holding ca glue finish materials to working around the apartment. It has a place for text, if you want to identify what is in the holder. Also, if you are looking to print a larger holder, each part can be rendered and save separately.
The big thing to watch out for is the corner radius, if you change it from 3 you will have to determine a new optimum fitamount. I have tried it on both extruders on my printer and it seems to be identical, not surprising.
Also, this is an openscad file, so you will need openscad to modify it. https://openscad.org/index.html
The stl is a 35x55x75 mm box,
the partsholder bottom and partsholder top are a 95x60x150 box.
PartsHolder.scad has been updated to make the holder more dimensionally accurate. Also, I am adding a credit card holder for the cards you don't carry around (Prime Shopping Card).

Actually, I have a Creator Max, but Thingiverse doesn't have that option. Most of the print settings don't matter, it's a simple print to execute.
