This is a removable mount for a (slightly modified) AnyCubic Kossel.

The mount clips onto the end effector and holds a BLTouch underneath for delta calibration and mesh bed levelling. Two M3x5mm screws self tap into the under-size holes in the mount to attach the BLTouch.

The Fusion 360 model can be downloaded (and hence customised) here: https://a360.co/2KeeqeZ

The Z-Offset for me was 49.50mm, but I have modified my Kossel with an E3D V6 hotend which sits higher up than the stock hotend.

I recommend measuring your offset as it will vary. The M114 (reports current XYZ) command is useful for this.

If bed leveling is bad, use a raft. This model is really not fussy with print settings. Will need support though.
