This is a modified V0.0 Sherpa mini tool head to mount the Libra mini extruder. 
I have modified it to use threaded heat inserts. 
BOM: 
7x M3x4.2mm x 5mm threaded heat inserts.
2x M3x 24mm screws
1x M3x14mm screw
original long screws and nuts
22mm PTFE tube

Assembly:
Insert the threaded heatserts into: 
Fan-1 and Fan-2 x2 heatserct
Body-1 x3 heatserts
- 1x to secure Body-1 and Body-2. 1x for the belt retention bock. 1x for the front fan.
Body-2 x2 heatserts
- 1x for the belt retention block. 1x for the front fan.


Use the M3x14mm screw to attach Body-1 and Body-2. 
reuse the long screws and nuts to attach Fan-1 and Fan-2 to the body assembly.
*** From the bottom *** Use the 2x M3x24mm screws to attch to the belt retention block. 

Cut and use 22mm of PTFE tube between the tool head and extruder.
