Legally Distinct V3.1 - 150g Robot

thingiverse

This is version 3.1 of my antweight drum spinner, 'Legally Distinct'. Version 2.1 works fine but is a little overweight (4 grams to be exact). The parts for this are entirely the same, but I've made it less chubby in an attempt to save weight. I have a feeling it will have saved more than 4 grams. (I was right, currently sits at 139 grams!) The changes in this version include: - General decrease in size - Space for electronics moved to the back - Lower mounts for the switch to enable inverted driving - Open spaces on the chassis to save weight - Increased space for wheels NOTE - This version *does* drive inverted, however the drum will catch on the floor while inverted, should be able to use it to self-right, but I haven't tested that yet. I've used a Malenki Nano ESC in my build, can't guarentee a standard Dual ESC will fit alongside a receiver but it likely will. The files are a little messy...I will try and get around to tidying them up but for now it does the job. V3.2 Updates Added wedges on top of the chassis to prevent the drum hitting the floor while inverted.
