Free standard shipping on orders over $25 to Canada, the UK, EU, Japan, Korea, Australia and most other countries (5–15 days); to the United States at carrier cost from $11.99. Because every set is printed to order, allow the lead time above before dispatch. 7-day returns; a mis-printed or warped part is reprinted or refunded with shipping covered. Import duties, where charged by your country, are paid by the recipient — these parts are declared Singapore origin, HS 8487.90.\u003c\/p\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003ch3\u003eWhat is not included?\u003c\/h3\u003e\u003cp\u003eEverything that is not plastic: the three 4-inch omni wheels, three STS3215 servos, the Waveshare motor control board, the Raspberry Pi or Jetson, the M2\/M3\/M4 screw set, and a battery. We sell the servos and the Waveshare board separately.\u003c\/p\u003e\u003ch3\u003eWhy is no battery supplied?\u003c\/h3\u003e\u003cp\u003eLithium cells are restricted in air freight. The set includes mounts for both the 12 V battery and a 5 V USB power bank, so you can source either locally and bolt it straight on.\u003c\/p\u003e\u003ch3\u003eWhy would I buy this instead of printing it?\u003c\/h3\u003e\u003cp\u003eThe two base plates are 216 mm across and will not fit a 180 mm printer at all. Even on a 256 mm machine the full set is about 34 hours — a day and a half with the printer doing nothing else.\u003c\/p\u003e\u003ch3\u003eDoes the SO-101 arm bolt straight on?\u003c\/h3\u003e\u003cp\u003eYes. The set includes the LeKiwi-specific modified follower-arm base, so an SO-101 follower mounts to the top plate without any extra adapter.\u003c\/p\u003e\u003ch3\u003ePi or Jetson?\u003c\/h3\u003e\u003cp\u003eBoth mounts are in the set, so you can decide later. The upstream LeKiwi build uses a Raspberry Pi 5; the Jetson holder is there for people running heavier on-device inference.\u003c\/p\u003e\u003ch3\u003eIs the geometry modified?\u003c\/h3\u003e\u003cp\u003eNo. These are the upstream LeKiwi STL files printed unmodified, so the official assembly guide and the LeRobot lekiwi configuration apply exactly as written.\u003c\/p\u003e\u003ch2\u003eAttribution\u003c\/h2\u003e\u003cp\u003eThe part geometry is the open-source LeKiwi design by SIG Robotics at UIUC (Pepijn Kooijmans, Manav Chandaka, Bhargav Chandaka, Gloria Wang, Advait Patel), released under the Apache License 2.0, printed here unmodified.
