The OSSM wired remote control provides a compact, handheld interface for your machine. This page shows exactly what to print, the slicer settings to use, and the minimal hardware required to assemble the wired remote enclosure.

Prefer a different look? Alternate knob styles are available in the “Non-standard” folder of the source repository. Print any two compatible knob variants.
Use these settings for all enclosure parts unless otherwise noted:

Walls3
Top/bottom layers4–5
Infill25% Gyroid or Crosshatch
SupportsYes — Auto (cover off, internal cavities clear)
MaterialPLA+ or PETG
Bed adhesionSkirt; add a small brim for knobs if your bed adhesion is weak
Estimated filament usage for all parts is approximately 70 g.
Orientation recommendations:
  • Body: Flat face down so the encoder holes point up. This keeps the front surface clean and strong around the controls.
  • Top Cover: Flat face down.
  • Knobs: Print face down for best surface finish on the top.
Dry-fit before final assembly. If bolt holes feel tight due to printer tolerances, chase them with a 4.0 mm drill bit by hand rather than over-tightening fasteners.

Bill of materials (enclosure)

ItemQuantityNotes
M4 button cap bolt, 6–8 mm length2Secures top cover to body. Choose length based on fit; 8 mm is commonly used.
If you purchased the “OSSM Remote PCB Only,” it typically ships with a 7 ft CAT6 cable and two M4×8 mm fasteners you can use for this enclosure. If you received a different length, use any two M4 button cap bolts between 6–8 mm that do not bottom out when the cover is installed.

Assembly overview

1

Print and prep the parts

Slice and print the body, cover, and two knobs using the settings above. Remove supports and lightly deburr holes.
The cover sits flush on the body and bolts pass through the cover freely by hand.
2

Test fit the electronics (dry fit)

Place your remote PCB into the body to check clearance around the encoder shafts and cable exit. Adjust any stringing or bumps so the PCB seats flat.
If a knob rubs the cover after assembly, add a 0.2–0.3 mm Z-offset shim under the encoder or lightly sand the underside of the knob.
3

Install the knobs

Press-fit the printed knobs onto the encoder shafts. They should be snug but not require force that might stress the PCB.
If the fit is too tight, do not force it. Warm the knob slightly with your hands, or scale it to 100.5–101% and reprint.
4

Close the enclosure

Place the top cover, align holes, and fasten with two M4 button cap bolts (6–8 mm). Do not overtighten.
Knobs rotate freely without scraping, and the cover sits flush with no gaps.

​
Troubleshooting

Use 6 mm bolts instead of 8 mm, or add a thin washer under each head.
Check that the PCB is fully seated in the body. Add a thin shim under the PCB standoffs or lightly sand the underside of the knobs.
Lightly ream with a 4.0 mm drill bit by hand. Do not use a power drill inside the enclosure.
You’ve now printed and assembled the wired remote enclosure. Connect the Ethernet cable to your OSSM and you’re ready to play.
