​
Bill of Materials

If you purchased the “OSSM Remote PCB Only,” it typically ships with a 7 ft CAT6 cable and two M4x8 mm fasteners.

​
Assembly

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.
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 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.
