Glock 20/21 Frame dd20.1 Details
Are you looking for a new challenge in 3D printing? How about building your own custom Glock 20 or Glock 21?
The dd20.1 is a 3D printed gun frame for two “big boy” Glock models that are popular among gun enthusiasts.
The G21/20 are known for their power and reliability, and building your own using 3D printing technology can be a fun and rewarding project.
The dd20.1 Glock 20 is the 3D printed 10mm variant often referred to as the “bear killer” for its stopping power and size.
The black PF45 Large Frame 80% pistol frame by Polymer 80 is the perfect base for your next G20SF (10mm) / G21SF (.45) handgun build.
This frame is also compatible with the Glock 21 .45 ACP variant is often admired for its use in two world wars.

Glock 20/21 dd20.1 Tech Specs
Required Parts for the Glock 20/21 dd20.1
Prerequisites
- DD17.2 spec rails
- Full-size gen 3 locking block (same as DD17.2)
- Gen 5 Glock takedown lever spring (many pen springs will work, should be around 3mm x 10mm)
- Large frame Glock 21/20 lower parts kit (.45/10mm)
- Large caliber magazine of your choice
- G20/21 compatible upper
Materials Required
The dd20.1 requires basic gunsmithing tools and a 3D printing setup.
Using a dialed-in Ender 3 with widely available PLA+ filament will get the job done.
Tools Required
- Gunsmithing Punch Set
- 3D Printer
- Slicing software with a decent computer
- Drill bits for cleaning out holes.
- Hammer
- Flathead screwdriver
Suggested 3D Print dd20.1 Settings
The slicer settings for the 3D-printed Glock 20/21 are similar to the majority of setups for other 3D gun builds:
Nozzle: 0.4mm
Layer Height: 0.16mm
Temp: 220/60C
Infill: 100% (or 999 walls)
Supports: On/full (tree supports are ok) – use a close support interface gap. Your interface gap should not be larger than 0.16mm unless you know what you are doing with your setup.
Cooling fan: 20% normal, 50% on bridges. Off for the first 10 layers. Keep the fan low to prevent warp.
Bed Adhesion: gluestick or hairspray or both
Filament
- PLA+ (eSun, Polymerk or simular
- Optional: Zytel (Requires Zytel compatible 3D printer setup)
