So you've decided to build an OSSM. This is a rewarding project, suitable for beginner and intermediate makers. There's clear documentation here to get the hardware in your hands -- let's get started.
## Step 1: Source Your Parts
The OSSM is a combination of a servo motor, metric hardware, 3D-printed parts, and a custom PCB. Before you print anything, you'll need to purchase the non-printable components.
**The easiest route:** order a kit directly from Research and Desire -- it includes the motor, hardware, PCB, and linear rail matched to the current build.
**Sourcing yourself:** the community Discord is full of makers who've sourced parts from AliExpress, Amazon, and local hardware stores. Check the full bill of materials to see exactly what you need.
Complete hardware list for the standard OSSM build.
The 57AIM30 "Gold Motor" and compatible alternatives.
Schematics and board design for the OSSM controller.
Source design files for modifying or extending hardware.
## Step 2: Print Your Parts
Printed parts can also be purchased from Research and Desire, but if you've got a printer, go ahead and get started. Each section below has print settings, STL files, and quantities.
The core linear motion assembly.
3030 extrusion stand with pivot arm.
Quick-release motor mount.
Wired remote control enclosure.
Adapters for attaching toys to the actuator.
Protective housing for the OSSM control board.
All OSSM print files are also available on MakerWorld.
## Step 3: Assemble
With parts sourced and printed, follow the build guide to put it all together. Wire the motor, flash the firmware, and you're ready to go.
Step-by-step assembly instructions.
Connect the Gold Motor (57AIM30) correctly.
Install the latest firmware via the web flasher.
Configure third-party motors before first use.
