“If you have to ask, you’ll never know. If you know, you need only ask.” - I contemplated leaving the summary as this one simple line quote to describe the model but instead will provide more details.

This design is an attempt to create a printable reloader for use with magazines from the MP5 family. I am not a professional designer/engineer, CAD expert, etc etc etc...purely novice and a hobbyist. This is a short time, quick design that allows me to use the same 3D printed loader with HK and POF metal magazines as well as polymer magazines such as those from AC-Unity.
Print tips are below and reference the screenshot uploaded or Prusa project uploaded:
PETG or ABS for solvent resistance, albeit PLA would work
Designed for .2 print resolution with a .4 nozzle, the finer the better!
If using Pursa Slicer print on 0.20mm QUALITY
Print 100% infill
Print with supports enabled on print bed only! I prefer .2mm interface pattern spacing with 1mm pattern spacing for PETG.
Optional: Use salt remelt method to add extra strength
Print the lid with the top facing up
Print the main body with the top facing up (aka pocket for the nut facing the bed)
Print the tensioner with the flat portion facing the bed ("U" shape)
Spring that is easy to find is a unistrut spring nut, just cut off the spring! Spring length is 33 mm/1.3 in uncompressed. We want some spring tension/pushback!
Use any screw that you would like that will fit the hole! Hole diameter 5mm, max length from bottom of head to end of screw should be 30.5 mm. Screw I used was a hex head, fine thread, with a length of 30.5 mm.
