Insulin Pen holder with space for 10 needles

I designed this minimal holder for my Smartpen and some needles so I don't have to take a huge amount of ‘stuff’ with me each time I leave the house - this holds all I need to go out for a meal or a short visit somewhere (OK, a bit overf the top on the number of needles, I admit!). There is nowhere on this to hold blood testing equipment, so really more useful if you're using Flash or CGM monitoring.

It's designed to fit the Novopen Echo Plus or the Novopen 6 and 10 BD Viva needles. 

It holds 5 needles down each side - sometimes I use one side for new needles and the other to store used ones till I get home and can put them in a sharps bin!

I printed this on my Ankermake M5 using Sunlu Meta PLA at 0.2mm Layer height, WITH supports.
