Important! I made this model for a friend without having access to actual penfill cartridges. I have used accurate dimensions provided to me, but I have not been able to actually test it with real cartridges. I used a printed one 😅. Please provide feedback on how well this fits. The dimensions I used are as follows:
Total cartridge length including cap: 67.13 mm
Cartridge body diameter: 11mm
Cap length: 9.7mm
Cap diameter: 9.16mm
Length clerance: 1.6mm
Diameter clearance: 0.8mm
Press fit two 5mm x 5mm magnets in the hole in the center. Mind polarity.
If your printer's calibration is a bit off, you can glue those in place if the hole is too big, or drill them out with a 5mm drill if the hole is too small.
I do not use insulin myself. Any feedback on how to improve this model from the people who actually use it, is much apreciated.
There are multiple bodies in the STEP and STL file. Split them up before printing. The STEP file also contains the placeholder cartridge. You probably shouldn't print that.
I included separate TOP and BOTTOM STL files for your convenience.
The top part is marked with ridges to hopefully prevent you from opening it upsidedown.
Please post a make if you like this model.
