Suction Cup and Motor mount for Drawbot

This is a model of a suction cup and stepper motor mount I created for use with Andy Wise's drawbot: https://github.com/andywise/drawbot.And is an alterative for this part if you're using the suction cups mentioned below: https://www.thingiverse.com/thing:3054707NOTE The only part here on thingiverse is the motor mount. The suction cup and stepper motor were only used for getting scale size to design the mount so I'm not including them here.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, 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=1Since these cups are a lot different than the original ones I needed to model out new stepper motor mounts. Also, I wanted to remove as little 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 I made my model for the motor mount arm. Also, the screw mount face on the stepper motor model I'm using do not fit the nema 17 face plate layout exactly. I found the exact dimensions for a nema 17 face mount and added the accurate dimensions.
