Case for injector pen

thingiverse

I designed a travel case for an injector pen, with a hinge using 1.75mm filament through the holes. The latch is designed for a magnet, but I'm considering a purely mechanical latch instead. The compartments for the injector needle/canula are sized for NovoFine 0.25x6mm cartridges, but the fit is a bit loose, because I struggled to get the measurements exact. As such, they are unfortunately not held in place. To reduce that, I've adjusted the lid to make the internal cavity smaller. However, I have NOT printed and tested the new lid to confirm it fits. What I did instead, due to time restrictions, was to glue a sponge with about 10mm thickness to the lid to keep everything in place.
