We used “silk” PLA filament which gives this prop a distinctive shimmer, resembling the cartoon item. Photos here show light green, but a darker jade green also looks good.

3D Parts for Total Conversion Weapon

3MF files for 3D printing will need to be oriented in your slicing software for FDM style machines. Parts are designed to 3D print without any support material.

  • ray-handle-left-hand
  • ray-handle-right-hand
  • ray-led-holder
  • ray-middle
  • ray-nose
  • ray-tip
  • ray-top

3D Parts for Talking Computer

Parts below are designed for the talking computer verison.

  • melon-bottom
  • melon-handle-left-hand
  • melon-handle-right-hand
  • melon-keyplate
  • melon-switch-holder
  • melon-top

Each set includes both a right-handed and a left-handed grip — you only need to print one or the other. These place the slider potentiometer in a different position for better comfort.

Parts for Both Props

Parts list below are required parts that can be used in both versions of the prop. 

  • feather-pcb-mount
  • pommel-handle

Slicing Parts

No supports are required. Slice with setting for PLA material. 

The parts were sliced using CURA using the slice settings below.

The handle for the Total Conversion Weapon will need to be rotated 15 degrees (Y-Axis) in order to sit flat on the bed.

  • PLA filament 220c extruder
  • 0.2 layer height
  • 10% gyroid infill
  • 60mm/s print speed
  • 60c heated bed

Design Source Files

The project assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, STL and more. Electronic components like Adafruit's board, displays, connectors and more can be downloaded from the Adafruit CAD parts GitHub Repo.

If building both props, it might be best to do them one at a time. While it would seem to make more sense to assembly-line the work for both, some of the parts (both electronic and 3D-printed) are very similar…if mixed up, you may find yourself having to dismantle and repeat several steps over.
