Customizable box for ER 11 collets or similar

<hello world!>
I recently bought a 15 pcs set of ER11 collets from Banggood for my spindle. They came in individual boxes all wrapped together in plastic film. Since I had to make a box for them I made it in Openscad so it can be easily modified for other uses.

I've printed this in PETG without supports, brims or rafts, with a 0.5 mm nozzle at 0.2 mm layer height without problems. The tolerance was a bit low and I had to file the lip of the lower part to make both parts join, so you might want to play with that value in the scad file to suit your needs and printer capabilities.
