Summary Printed a copy of the P4 holster and it fit great! But I wanted a bit more access and stiffness in the sides holding the squirt in, so I beefed those up, added some very small gussets on the bottom shelf, just in case, rounded some edges, cut out some finger recesses in the top and bottom, and put just ever so small a bevel on the belt clip itself so it didn't drag as much when first putting it on. Enjoy! Print Settings Printer: Anet A2 Rafts: No Supports: Yes Resolution: 0.2 Notes: If you print with 4 wall's it's essentially 100% fill anyways, which I recommend. Being I printed without a part fan, I used supports touching the build plate only, which worked great. I shouldn't have to say it, but a brim is most likely a must as well.
