Insulin Pen/Needle Containers

I designed these to carry my insulin pen and needles for road trips. Each opening will hold a pen or up to 8 needles. To get 8 needles to fit, stack them alternately right side up, then upside down. I made double, triple, and quadruple for you to choose from.

Update 8-20-22: I have had requests to lengthen the containers to fit certain insulin pens. If you need one longer, there is an option in all slicers to change the dimension of the Z height. Use this function to make the cap taller to fit your pen. This should solve your problem.
