Summary

This is a model of a spray paint can. The original was designed as an interface for my 3D drawing program. It can hold a wireless mouse. The cap conceals a Radio Shack push button which I wired to the original mouse. The body of the can is a poster tube mailer I cut down to approximate size.

I have also included a full version of the can, although it might be too tall to print on many printers at full size.

Instructions

Print a mouse controller

If you want to print something similar to my original, print the top, bottom and cap models. I am only using the mouse as a clicker for my code, not dragging or scrolling. You could also place another electronic device inside instead of the mouse.

Cut down a mailing tube to size. I used something similar to this.
The button is a one of these from RadioShack. Be careful because once you put the button on it might be difficult to get back off.
I superglued mine so it wouldn't wiggle around.
The mouse is secured in some foam. I used a Logitech M325 wireless mouse, which is about 20 bucks online.

If you want to print a solid can

The can is about the size of a real spray paint can so you might check that it fits on your print bed.
