Anycubic i3 Mega Dremel Mount

If you've ever wanted to convert your Anycubic i3 Mega into a CNC milling/engraving machine, then this is the part for you! This mount allows you to put the end of a flexible shaft (which you can connect to a Dremel or other rotary tool) on the X carriage.

There are two parts, the base is what you slide into the universal mount. Secondly, there is the clamp that attaches to the base. You can bolt this clamp whilst holding the end of the flexible shaft in position.

The base has six cut-outs, where you can slide in some M3 nuts. For bolts, I used M3x16mm.
I used a rotary tool from AliExpress, which you can buy from the link below.
