Eli Lilly Autoinjector Holder

I'll call this a remix even though I only used sjones16's design as inspiration and rebuilt the whole thing from scratch. In comparison - I changed the dimensions over-all to be slightly more .4 nozzle friendly, corrected the off-set geometry of the clips so my OCD would calm down about things being even, rounded some edges, put in some supports and speed holes on the main frame, and created some optional glue-in vertical supports.

Assembled this holds 12 of Eli Lilly's autoinjector pens that they use on many medications, such as Trulicity and Monjarno. ID on the clips is 19.5mm and assembled the total top-to-bottom height is 84mm (clearance necessary between features on the pens), so any other manufacturer's pens that fit that should work as well. If you need different dimensions let me know and I'll be happy to re-size it for you.

Print Settings

Printer: Ender 3

Supports: Yes

Resolution: .2

Infill: doesn't matter, all walls

Filament: Hatchbox PLA Pure White

Notes:

I printed with a brim because of all the on-the-bed geometry. It was a pain cleaning out out, but came out successfully. Be careful with your slicer settings, as the inside of the little reinforcement bit on the clip (near the ends, where there's a bit more material) may try to print before the walls go down, which unless your adhesion and z-offset are perfect will mean lots of little lumps that the printer eventually goes over. I had a few of these pop loose and get melted on to the print head, which translated to a bunch of stringing that I had to run over with an xacto and then wave a torch over the whole thing to melt away. If your printer bridges well, supports are unnecessary, but might be worth enabling just so the holes and arches come out properly.
