#### Description
|
||
|
|
This is the (Glock) G18 Extendez 30 Round Magazine by Ivanthetroll. This magazine is 3D-printable and includes the G18 body, follower, floorplate and locking tab.
|
||
|
|
|
||
|
|
This project represents over 500 hours of time in CAD, over 250 hours of 3D printer running time, over 1000 rounds of ammo, all over the course of six months - plus a few more hours and 100 more rounds to develop the Extendez :). The end result is worth it - a 3D printable Glock magazine that cost next to nothing to print, will last several hundred rounds, can be printed on essentially any FDM/FFF printer, and requires little to no post-processing.

Below are instructions on printing and troubleshooting the Menendez Mag series.
|
||
|
|
|
||
|
|
#### What you'll need:
|
||
|
|
|
||
|
|
* PLA (Optionally Nylon [645 is tested good], PETG). I recommend PLA, as it is cheap, easy to print, and is what I designed the mag in.
|
||
|
|
* A printer capable of printing PLA (or the plastic you choose to use). The Creality Ender 3 is capable of printing these mags, and costs only 200 bucks. A guide to dialing in your printer can be found here: https://jstark1809.keybase.pub/DetDisp_3D_Printing_Guide.pdf?dl=1
|
||
|
|
* An appropriate Glock mag spring - use factory-spec Glock mag springs (not PMAG springs). These can be had cheap from Amazon, The Official Glock Store (NOT Glockstore.com!!!), Wilson Combat, AliExpress (the springs usually come with a baseplate extension).

### Print Settings
|
||
|
|
|
||
|
|
- Orientations
|
||
|
|
Note that the included STLs are scaled and oriented correctly!
|
||
|
|
|
||
|
|
- Print mag body upright, no supports.
|
||
|
|
- Print baseplate bottom down, no supports.
|
||
|
|
- Print locking tab bottom down, no supports.
|
||
|
|
- Print follower upside down, with the tallest flat portion to the print bed. Use supports from print bed, but not full supports.
|
||
|
|
|
||
|
|
- Print Settings
|
||
|
|
I recommend that you print in eSun PLA+, don't get too upset when you print it in ABS and it works poorly.
|
||
|
|
|
||
|
|
- Nozzle Temp - 230C
|
||
|
|
- Bed Temp - 60C
|
||
|
|
- Brim - ON
|
||
|
|
- Supports - NONE
|
||
|
|
- Layer Height - 0.15mm
|
||
|
|
- Shells (aka perimeters) - 4 inner/outer (this may not be necessary, but works well for me)
|
||
|
|
- Bed prep - Gluestick, optionally on top of Kapton Tape.
|
||
|
|
|
||
|
|
### Troubleshooting
|
||
|
|
Mags may feed poorly at first. This is because the mag lips are reinforced beyond what PMAGs or Factory mags are.
|
||
|
|
Dry cycle (or live fire) a full mag through it if it has issues feeding. This will solve rough feeding issues.
|
||
|
|
Printed mags will wear out. Their rate of wear depends entirely on the user.
|
||
|
|
If you feed rounds into the mag in a manner that drags the round along the mag lips, you will cause excess wear on the mag lips, which will wear the mag out.
|
||
|
|
Testing has netted a mag that is good for at least 500. Make sure to load each mag carefully as to not scrape the rounds along the mag lips when loading.
