Shot Glass Holder for xTool RA3

This improved jig is designed to hold 1.5oz shot glasses in the xTool RA3 while providing a more secure grip and greater working area than the original jigs that are included with the RA3. There are two versions of the model, one with magnets for easier operation and one without magnets for simplicity.

When using the original rubber coated jigs that came with the RA3 I had issues with glasses becoming loose when too much clamping force was applied. The original jigs are also quite long at 14.5mm which reduces the amount of work area where it clamps onto the part. 

This was designed to hold shot glasses with a diameter of ~48.75mm at the largest point, however it will probably work with other shot glasses in that general range. I have also reduced the length of the jig, so the improved model only takes up 4.5mm compared to the original 14.5mm. The magnetic version is meant to easily snap in and out of the chuck and uses 4mm diameter magnets that have a max length of 5mm. I use three 4x1.5mm magnets stacked on each other, however it should also work with any other combination under 5mm or even a single magnet. A version without magnets is also included as it will work fine without.

Parts needed for magnet version

• 4mm diameter neodymium magnet (max length 5mm)

  • Can be a single magnet or stacked to reach 5mm
