A couple of versions back, I compared the weight when I had my machine apart. The original wooden part with all the hardware including the wheels weighed interesting enough at 1 lb even (that was with the solid V wheel). That did not include the weight of the heat bed, glass or heatbed mounting hardware. My version was 11.8oz with the same hardware attached. I have added some more plastic since then, but should be a little less than the wooden part.
