3 lbs 9 oz (Quite obviously this could not be a government project or the weight would be several tons, even after the traditional removal of common sense and functionality.)
8 lbs, 1 oz Some info to help y'all out: The box shown appears to be for shipping 1000mm length v-slot rails. A single box might fit 3x3 (9) rails squished tightly together (can anyone confirm this?), but I've only received them packaged as 2x2 (4) rails, with some room left over for screws etc. 1kg is the most common weight of a roll of 3D printing filament. 1kg = 2.2 lbs (2 lbs, 3.2 oz) or 0.4545kg = 1 lb The length-to-weight ratio of 2020 v-slot is approximately 1000mm:1lb My 40mm Nema 17 36.8oz.in(26Ncm)0.4A Stepper weighs exactly the same as my 500mm length of 2020 v-slot The standard 48mm Nema 17 stepper motors found in 3D printers are usually around 12-14 oz. (Apparently, Amazon's shipping weight is wholly inaccurate) My 24v 240W DC Power Supply is about 2 lbs. My Duet WiFi weighs 0.20 lbs or 3.2 oz.
