This guide covers the 3D printed parts required to build a RADR wireless remote.

​
Required Parts

PartQuantityNotes
Top Housing1Main body with display cutout
Bottom Housing1Battery compartment and mounting
Buttons3Under-screen buttons
Encoder Knobs2Left and right encoder caps
Power Switch Cap1Optional cover for power switch
These parts print nicely with the following settings:
ParameterRecommended Value
Layer Height0.12mm (for smooth curves)
Wall Thickness4 layers
Infill20-30%
MaterialPLA, PETG, or ASA
Using your slicer’s auto layer height function will balance resolution and speed.

​
Top Housing

The top housing requires significant supports due to the display cutout and internal features.
  • Print with the display opening facing up
  • Enable supports for overhangs
  • For Bambu printers, the included 3mf file has recommended support settings

​
Remote Clip (Optional)

If you’re printing the wireless remote clip for mounting:
ParameterRecommended Value
Wall Thickness6 layers
Infill40%+
The clip needs extra strength to handle repeated mounting and removal.

​
Multi-Color Printing

Many of these parts contain multiple bodies to allow multi-color printing. This is optional—you can print all as the same color if you don’t need to see the LEDs through the housing.

​
Transparent Sections

The following areas benefit from transparent or translucent filament:
AreaPurpose
Power indicatorShows charging LED
Button status indicatorsShows button backlighting
Knob backlight areasShows encoder LED colors
Multi-color printing is purely aesthetic. The device functions identically with single-color prints.

Assembly Tips

Test fit all parts before final assembly. Some printer calibration variation may require light sanding.
The encoder knobs press-fit onto the encoder shafts. Apply even pressure when installing.
Don’t over-tighten screws into 3D printed parts. The threads can strip if overtightened.
