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)
