The structural parts of the open-source SO-101 arm (The Robot Studio / Hugging Face LeRobot), printed from the official files in Melbourne and shipped in 3–5 business days. Printed parts only — add the standard STS3215 servo kit and build. More open-source robot parts join this shelf as they are test-printed.
Every printed part of the open-source SO-101 / LeRobot arm — follower (11), leader (12) or the pair (23) — printed to order from the official files. Servos not included.
◆ Printed parts only. Servos (6 × Feetech STS3215 per arm), driver board, power supply and screws are not included. The SO-101 is an open-source design by The Robot Studio (Apache-2.0); Formada3D is independent and not affiliated with The Robot Studio, Hugging Face or any servo maker. Pictures are renders from the official files until our test-print photos land.
Designed and printed in our Melbourne workshop, shipped Australia-wide.
Magnetic drawers, snap-pin joints, label-forward angles — tested on our own bench.
Pick your filament colour on every rack — matched across the whole line.

Honest buying guides from the workshop — sizes, materials and what actually fits, written from our own bench.
Every photo below is a real Formada3D print in a real home — no renders.
Every 3D printed structural part of the open-source SO-101 arm: 11 parts for a follower, 12 for a leader (with handle and trigger), 23 for the pair, printed to order in Melbourne from the official Apache-2.0 files. You add the servo kit (6 Feetech STS3215 bus servos per arm, a driver board, power supply and USB cable) and the screws that come with the servos.
The follower is the arm the robot moves; the leader is the one you hold to teach it. LeRobot teleoperation and data collection need the pair; running a trained policy needs only a follower.
PLA Matte in nine colours, Matte Black by default. PETG-CF for all-day lab arms is quoted on request.
Yes: five or ten pairs, PETG-CF, invoices and purchase orders are quoted on the business site's SO-101 page.
No. The SO-101 is their open-source design (Apache-2.0); we print the published files and name them only to say what the parts fit.
