Description
Solid mounts for the bigger motors
Once a project moves beyond small toy motors, the motor needs a proper bracket. This pack has two of each for the common larger sizes: 37GB gear motors used in robot cars, 545/550 and 775 DC motors used in drills, pumps and fans, the big 895 motor, and the NEMA 17 stepper used in 3D printers and CNC machines. It complements our Motor Mount & Bracket Pack, which covers 130-size and other small motors.

Shipping
Standard shipping: $9.00 for the first item, +$1.80 for each additional item. Free shipping on orders over $260.
We ship worldwide, by default with economical international post (UPU / China Post small packet) to keep shipping costs low. Orders are usually handed to the carrier within 2–5 business days, and economical international post then takes about 10–30 business days to arrive; these are estimates, not guarantees. Delivery time depends on the destination and on postal and customs handling. If you need your order by a certain date, email us before ordering: faster shipping can be arranged, with the extra cost charged at the carrier's actual rate. Items that contain batteries or magnets are marked on their product page and ship by a special carrier line; some countries and regions cannot be reached by that line, and if yours is one of them we refund the order in full.
Customs & duties
Import duties, taxes and customs requirements depend on the destination country, the shipping route and the local customs office, so we cannot say in advance whether any will apply to your parcel. Customs may hold a parcel, ask for more information, or ask for duties or taxes to be paid, even when the declared value is correct. If you have a question about your country, email us before ordering.
