+Zodiac BMO Stealthburner Toolhead
+=================================
+
+A modified toolhead for use with the Zodiac BMO Hotend and compatible with RC1 of Stealthburner.
+It was created from the original RC1 Stealthburner Phaetus BMO Toolhead files.
+If changes after RC1 of Stealthburner make this mod incompatible, I will provide updated files based on the official Stealthburner CAD files.
+The official [Zodiac3D CAD Model](https://zodiac3d.com/pages/copy-of-datasheets) of their BMO Hotend was used for reference.

+
+Notes
+-------------------------
+For optimal fit it is very important that your printer's dimensional accuracy is nearly perfect. Especially Pressure Advance has to be tuned right.
+Even then it is still a very tight fit, when putting in the hotend. That ensures that it cannot twist or wiggle.
+One handed nozzle changes should be possible, but are generally not recommended.
+
+The bowden tube length from top of the toolhead to the heatbreak of the hotend is around 31.2mm. Take that into account when calculating the total bowden length.
+(E.g. Clockwork2 needs 11mm above the toolhead, so that accumulates to a total bowden length of 42.2mm, when using Clockwork2.)
+
+Test prints were made with standard ABS, ABS+ and ASA Carbon.
