XTool F1 riser base (or feet) to raise the F1 higher to allow the rotary module to slide under the base, which allows you to engrave larger cups. Also allows a little more engraving are on mugs with handles as the handle can turn a little into the space if the base plate is removed. the feet are designed so that the rotary module should be pushed to sit flush with the inside of the front feet. There are cutouts on the bottom to fit thin rubber pads (about 1-2 mm pads). You can also change the orientation of the stepper motor on the rotary module so that the wiring plug faces up and gives you more room to push the rotary module to the left. You will need M4 screws to attach it to the base (don't recall the length, but probably about 20 mm long). The screw holes don't need support, but added support for the cutouts for the rubber pads.
