Everybody loves to dock :)

This is an easy to print magnetically retained magazine holster system built around a Tek Lok style connector. This is sized for Glock 9mm full sized (17, 15, 10) magazines. Everything is built around M4 screws. This holster backplate + body combo is set up to attach directly to a Tek Lok connector. I made these to go on my IDPA Link Belt System (LINK)

--Parts list--

1 x M4 countersunk screw pack - (Amazon LINK)
1 x M4 heat set threaded insert pack - (Amazon LINK) 
1 x 26ish mm 60lb countersunk magnets - (Amazon LINK)
1 x tube of Superglue - Wherever you get superglue from if you are using TPU for the body. I am new to threaded inserts in TPU so there may be better solutions to this I am not aware of. 

You will need washers / nuts for the magnets but those usually come with the screw packs. The ones I linked above have them in the same box. 

--Parts List per Magazine Pouch--

4 x 6mm M4 threaded inserts (I used superglue for TPU, heat set like normal if not TPU)
2 x M4x10 (Top 2 holes) for the holster body to connect through the backplate to the Tek Lok connector
2 x M4x12 (Bottom 2 holes) for the holster body to connect though the backplate to the Tek Lok connector.
2 x M4x10 to attach the magnets to the backplate. 
2 x 26ish mm countersunk magnets
2 x M4 washers / nuts

--How to assemble--

0) Print the backplate
1) Print the holster body. I roughed up the inside of the holes with some sandpaper and made sure it was free of all support material. It is tricky with TPU as TPU bonds super hard with its supports but do your best. Make sure to pop out the little drainage hole on the bottom. 
2) Put the heat inserts into the top 2 and bottom 2 holes of the body. 
---2A) IF you are using TPU, put a healthy dollop of super glue into the hole. Insert a screw partially into the    threaded insert and wiggle that sucker in there. It should be very tight and you will have to do some serious wiggling. 
---2B) IF you are using PLA or another material, insert it via soldering iron like normal. 
3) Install magnets onto backplate - the tolerances here are loose as 26mm magnets are not all the same (sometimes not even the same in the same pack)
4) Snap the backplate onto the holster body.
5) Install the screws through the Tek Lok connector into the threaded inserts. Voila, magazine pouch. 

--Print settings--

Body - 100% infill / 0.12 layer height / print on fuzzy skin / Overture Black TPU.
Backplate - 100% infill / 0.12 layer height / ESUN Orange PLA+

--Tips--

1) IF you are using TPU, make sure to really clean the heat insert holes since TPU bonds so strongly to its supports. 
2) IF you are using TPU, rough up the inside of the holes a little bit with some sandpaper so the superglue bonds better to it. 
3) I extended the holster placement to the bottom of the Tek Lok connector I use and there is a small gap but it is there by design. When you pull a magazine out of a holster, it is never perfectly straight. This gap allows the body + backplate to flex just a little bit and takes some of the strain off the front lip of the holster body so it doesn't wear out quickly. 
4) If you rub your mags down with a silicone rag, you should take that same silicone and wipe around inside of the holster. It will be very slick :)

--Other magazines--

I have included a separated body (back part and front part) with one front part being completely solid and the other one having the glock magazine sized hole. Adjust how big the hole needs to be, snap the adjust front and back pieces together, combine, and print.
