150G Drum Battlebot

thingiverse

Drum Robot. This is a 150g combat robot. I'm attaching the .STEP file as well for those who want to edit. Notes: The more infill you print the drum at the heavier it will be. I use 70% There is no need to enable support on the drum. There is a sacrificial bridge later you need to break with a screw but it should be very easy to do so. The only part that needs support is the motor bracket. The N20s are a snug fit in the chassis. But I use a zip tie just to make sure they are secure. Use M3 Heatset insert behind the drum to attach the motor holding plate. Use #3 Plastite screws for the top panels.
