Simple 6 model slim case to hold those Tyranids in, magnetic lid and has the option to add washers to hold the models if you glue magents to them.
Uses Ø10 x 5mm magnets in lid and M3 nut in the base, the washers are the M8 type.
Prints without supports, and depending on the magnets the lid stays on firmly!
I used a hot glue gun to seal the nuts and magnets into place, use super glue for the washers.
