This is a case for insulin pen and needles. The pen is Lantus Solostar and needles are 4 mm needles. Case holds eight needles, enough for a long weekend. I made it for my diabetic cat, hence the cat in the picture. 

Case size roughly: 185 mm x 80 mm x 23 mm

Requires two 8x3 mm circular magnets for proper function.

It is print-in-place. Fits 20 cm x 20 cm printbeds. Tolerances are real loose, because my printer is a little shit.
