Twin-Tube epoxy/adhesive/fill adapter for standard caulk gun

thingiverse

This is an adapter that allows you to use a standard caulking gun to dispense twin-tube epoxy/adhesive/fill cartridges like those used for joining Corian counter-tops. This is designed to use 3/8" dowels to connect the plungers to the gang and the length is determined by the size and the full-ness of the cartridge. Print the gang with a high fill percentage (near 90%) to increase stiffness. The initial priming of the twizzle style mix sticks requires a lot of pressure and the gang can flex favoring the larger side of the cartridge. you can make the dowel for the smaller plunger slightly longer to compensate or simply use some washers as shims. Once the twizzel stick is primed and flowing the flex of the gang is less of an issue.
