This adapter is specifically to mount the Nimble on the new PCB effector that Escher3D is developing with Think3dPrint3d. It uses a new hot end mount that is developed by E3D.
Have a look at the new effector [here.]
Simply bolt the adapter to the hot end mount and bolt the Nimble to the adapter.
In case your printer is in pieces, or you want perfect precision, you can also get this adapter via Shapeways.
Added Version 2 to the models. The method of attaching the Hot end to the PCB effector has changed, so the mounting method of the adapter needs to change. It is now done with 6.6 mm standoffs. The adapter has 3 holes for M2.5 and the PCB has 3 2.9 mm holes.
The adapter fits on top of the hot end and has a 5 mm deep hole in the bottom for the PTFE tube.
This way you clamp the PTFE tube into the hot end when you bolt the adapter down.
Alternate model has 3 integrated legs to make it easier to mount. Will be a bit more difficult to print, though.
Added a little pipe holder for use with a Berd-Air like part cooling system.
It is slightly off center to allow the LED in the corner to still shed some light on the printed parts. It uses the Magnetic ball bolts to clamp it to the PCB and has a little rest for the tubing. You can use a tie-wrap to clamp the tubing to the rest.
The standoff of 6.6 mm was not enough, needed to be 7.6 mm.
So changed the files to reflect this and you now need version V2.1 is you want the integrated legs.
Added version V2.2. The only difference is that the leg closest to the 6 wire black plug is lowered to be below the latch or clip of the plug. Thus making it easier to unlatch and less prone to breaking. For now only the STL as the real fix (turn the plug around) is easy to implement and will be probably changed in future versions of the Smart Effector.
Added version V2.4. I followed DJDemonD's suggestion and added a 12 sided hole in the bottom to lock the hot end mounting nut in place. Here is DJ's mount: https://www.thingiverse.com/thing:2740387
Also added a split version, with Top and Bottom half, so it can be printed and then glued together. You will need to add a little support under one of the bolt holes.
I didn't the Step files for that, as it is too easy to make that yourself.
Firebug alerted me to the fact that E3D now supply a plastic nut that is 17 mm wide across the flats, so I added a new Bottom Part and complete mount, to incorporate that change,
The Nimble Extruder
With an installed weight of less than 27 grams on your carriage/effector the Zesty Nimble is smallest and lightest extruder you can buy, it has ample torque and can be mounted in multiple orientations.
The Nimble is available from Zesty Technology.
