Suction Cup and Motor mount for Drawbot

thingiverse

This is a model of a suction cup and stepper motor mount that I created for use with Andy Wise's drawbot: https://github.com/andywise/drawbot. It serves as an alternative to this part if you're using the suction cups mentioned below: https://www.thingiverse.com/thing:3054707. **NOTE**: The only part here on thingiverse is the motor mount, and I'm not including the suction cup or stepper motor because they were only used for getting scale size to design the mount. When we decided to build out two new drawing robots for an event, I wanted to try different suction cups for mounting the motors. The harbor freight suction cups worked well initially but fell off over time, so I searched for and found these stronger suction cups: https://www.amazon.com/gp/product/B07Q7Y8WHG/ref=ppx_yo_dt_b_asin_title_o02_s03?ie=UTF8&psc=1. Since these cups are a lot different than the original ones, I needed to model out new stepper motor mounts. I also wanted to remove as little material as possible from the suction cup itself to get the desired latching functionality from the motor mount arm. So, I first made a scale model of the suction cup and then created my model for the motor mount arm. Also, the screw mount face on the stepper motor model I'm using doesn't fit the nema 17 face plate layout exactly. I found the exact dimensions for a nema 17 face mount and added the accurate dimensions.
