The Xolephant - MMU filament cutter for the Xol toolhead

BOM (in addition to the standard Xol trappings):
 

• 2x 25-30mm, 5mm diameter springs
• 2x 30-35mm M3 bolts
• 2x m3 heat set inserts
• 1x m2.5 nut
• 1x m2.5x8-10mm bolt
• 3x m3x6 bolt
• 1x #17 hobby knife blade
• 2x m3x8-10mm bolt
   

You will need to design a simple but sturdy block for this to push against to cut.  Add a move to your toolchange code that slams the lever against some block.  First, a slow move up, then a sharp snap.  

Fits rapido, dragon, dragon water hotends (and any others that use that four hole scheme and are less than the dragon water in diameter).  

The air vent holes in the side work with both the dragon water and the rapido
