title: Sourcing the parts
description: What to buy and 3D-print for a PhysiClaw rig — the full BOM, sourcing tips, and the custom STEP parts.
---

PhysiClaw's hardware favors standard, off-the-shelf parts — easy to source, low-cost, and reliable;
the custom parts are 3D-printed.

A full set of parts costs around **¥1,000** (RMB), excluding shipping. Before ordering, read through
the assembly manual to fully understand the hardware; when purchasing, check each item against the
bill of materials to make sure nothing is missing and quantities are correct — any omission means
another order and more time lost to shipping.

All suppliers listed are [Taobao](https://www.taobao.com) stores based in mainland China and require a Taobao account to view
product details. If you're outside mainland China, these stores may not ship to your region, and
prices may vary. Contributions of suppliers for other regions are welcome.

:::caution[3D printing process]
Print PhysiClaw's custom parts in black **[PA12 nylon](https://en.wikipedia.org/wiki/Nylon_12)** using powder bed fusion (**[SLS](https://en.wikipedia.org/wiki/Selective_laser_sintering)** or **[MJF](https://en.wikipedia.org/wiki/Multi_Jet_Fusion)**).
Common **[FDM](https://en.wikipedia.org/wiki/Fused_filament_fabrication)** printing tends to leave holes out-of-round and distorted, which throws off the fit.
