Testors square paint bottle shaker

This is an original design for a paint shaker holder for the square Testors paint bottles. It can be used with a jig saw, sawzall, or oscillating saw simply by attaching the holder to a blade that fits your saw. Some holes may need to be drilled into your blade to make it fit best. The screw holes are designed to fit bugle seat 6-32 screws with a flat head.

I cut a piece of 5mm foam for the bottom of the holder to keep tension on the bottle. You might wish to use 2mm foam as the 5mm makes the opening quite tight. Alternatively, you could just hold the bottle in with a rubber band.

This was printed on my Ender 3 with 20% infill and a Gyroid infill pattern.
