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\u003eServos, horns, cables, controller board, power supply and clamps. Add the SO-ARM101 12-servo set and the SO-101 Builder's Pack from this store and you have a complete arm.\u003c\/p\u003e\u003ch3\u003eIs the geometry the official design?\u003c\/h3\u003e\u003cp\u003eYes. These are the unmodified STL files published by TheRobotStudio for the SO-101, so LeRobot's so101 configurations and every community tutorial apply without changes.\u003c\/p\u003e\u003ch3\u003eWhy does it take 5–7 days?\u003c\/h3\u003e\u003cp\u003eA follower set is about 17 hours of printer time and a leader about 18. We print on receipt of your order rather than holding finished stock, so the lead time is real production, not warehouse handling.\u003c\/p\u003e\u003ch3\u003eWhy would I buy printed parts instead of printing them myself?\u003c\/h3\u003e\u003cp\u003eIf you own a printer and have two days of machine time, print them — the files are free and we link them. People buy this set when the printer is busy, when they have no large-format printer, or when a lab cannot justify the labour of support removal and insert fitting.\u003c\/p\u003e\u003ch3\u003eDoes Singapore origin matter?\u003c\/h3\u003e\u003cp\u003eFor United States buyers it can. Duty is assessed on country of origin; these parts are printed in Singapore and declared as such, rather than being China-origin goods re-boxed. Your own customs treatment still depends on your country and the value of the shipment.\u003c\/p\u003e\u003ch3\u003eCan I get PETG or a different colour?\u003c\/h3\u003e\u003cp\u003eYes. PETG and custom colours are available on request — email before ordering so we can confirm lead time, since colour changes affect how we batch plates.\u003c\/p\u003e\u003ch2\u003eAttribution\u003c\/h2\u003e\u003cp\u003eThe part geometry is the open-source SO-ARM100 \/ SO-101 design by \u003ca href=\"https:\/\/github.com\/TheRobotStudio\/SO-ARM100\" rel=\"nofollow\"\u003eTheRobotStudio\u003c\/a\u003e, developed with Hugging Face and released under the Apache License 2.0, printed here unmodified.
