Craft Paint Bottle Shaker

thingiverse

A variant of the paint bottle shaker I posted can shake up to two craft acrylic paint bottles at once and works great after testing. To assemble this one, place the bottles upside down in position without using rubber bands, although they held securely on their own - you might want to add some as a precaution. You'll need a 5-6 inch saw blade that's been ground or filed down to size. Two bolt holes are available but I found them unnecessary; instead, smear the blade with epoxy and hammer it into place until it's seated at the bottom. I've used this attachment about 10 times so far without any issues. WARNING: Since this device is attached to a power tool, use caution and follow safety guidelines - wear safety glasses, point the shaker towards a bucket or the ground, and exercise common sense when using it. Although designed with safety features to prevent bottles from flying out, accidents can still occur.
