CETME and HK flat bending jig

thingiverse

This is a printable bending jig for CETME and G3 receiver flats to both bend the flat evenly, and keep it properly shaped. It should work on all HK style flats, but I don't have any others on hand to test. The "Mandrel Filler" pieces should be installed once the flat is most of the way there. A complete rundown of how to use it can be found here: https://jeffstoybox.blogspot.com/2020/10/my-3d-printed-cetme-and-hk-g3-bending.html FOLLOW THE DIRECTIONS LAID OUT IN THE BLOG POST OR YOUR FLAT MAY END UP OUT OF SPEC. *Edit: If you got the very first upload, the Jig Rear file was wrong. It was a copy of one of the mandrel pieces by mistake and it is now the correct file. *Edit: I've also added one piece jig and mandrel files if you've got a really big printer. the internal tubes for the dowel rods are still there so if you don't want them to print you'll have to check Cura's "Union Overlapping Volumes" option. *Edit: Based on a user review, I recommend printing the two piece version, even if you have a big printer. Having two pieces allows you to adjust for length in case the holes in your flat aren't exactly on, or your printer prints a little out of spec.
