Mount for Euclid for the Ratrig toolhead beta 2. To fit this, you also need a new front piece for the toolhead, i.e. one that does not have the Pinda mounting tube. The new front piece is included.

I made this to make the head lighter, sturdier and more compact than what it would have been had I only designed a Euclid mount to fit the existing Pinda mounting tube. Cannot tell whether this makes any difference, I have no comparison data. Also, be aware that the Euclid docking will be rather high with this mount, so there is an Euclid dock to go with this mount in https://www.printables.com/model/1184770-euclid-dock-for-ratrig-v-core-31-and-rr-toolhead-b

The Euclid mount is designed so that it should slightly, very slightly push the PCB so that the front and back of the PCB are in a solid contact with the mount. A downside in some mounts seems to be that they allow the PCB to rock slightly, which decreases accuracy. 

With this setup the typical accuracy (repeatability) test with 10 samples is within 4um, with abt 1um standard deviation:

 

probe accuracy results: maximum 2.158750, minimum 2.155000, range 0.003750, average 2.157219, median 2.157344, standard deviation 0.001238
