Rigidbot e3d Underdog Mount v1 (reversible, single or dual, z-loss or zero-z-loss support)

thingiverse

UPDATE! I have added 2 new stl files, underdog_pt2_backside.stl and underdog_pt4_backside.stl. These are respectively .2mm and .4mm taller, and can be used to offset one hot-end slightly lower in a dual extruder setup for bed leveling when normal techniques fail to get it just right. You can use the regular front/smaller piece. Here is my latest e3d mount for the Rigidbot. This mounts under the aluminum plate allowing you retain the stock extruder mounting block. The short bowden tube on top of the e3d will align and fit into the old PTFE slot on the exturder block. This will work with both single and dual hot end and is reversible. Use stand alone for a standard lossy mount or use the included risers for a zero z-loss solution. FYI, I used a 1/8 drill to enlarge the holes used to attached the extruder side larger mount to the aluminum plate/extruder block. Additional screws I used: M3x16 M3x20 M3x50 (the risers are taller than my previous versions) When mounting on a lossy single extruder system their is one location where the mount is very close to a bearing bracket, but it does fit and works fine.
