+Assembled one of these, have some hardware bugs but will continue to bring this online instead of revisioning:
+
+- could use a third thru-bolt to get the planar constraint w/ the second half of the hotend-pinching clamshell 
+- loadcell to bowden connector does not clear (visible in CAD: move out or move up) 
+- m4 head-thru on top of loadcell on hotend not wide enough 
+- more pusher-part (extruder / top half) clearance to plate, notice misalignment / out of squareness at loadcell mount
