This is a mount for 2 single Nimbles.
Please don't confuse this with the "D-Bot Chimera/Cyclops adapter for the Dual Nimble using the printingSome carriage", https://www.thingiverse.com/thing:2459458.
I chose to buy 2 single Nimbles because perhaps I will try them later with a diamond hot end and then only have to buy 1 extra.
You won't need the "Groove Adapters" provided with the Nimbles. These would overlap each other in this arrangement. Part1 will replace them.
Part 2a is to be used with my "3-wheeled or Linear Railed Modular X-carriage (D-Bot Core_XY 3D Printer) ", https://www.thingiverse.com/thing:2206664
Part 2b is to be used with the original front plate of the "D-Bot Core-XY 3D Printer" by spauda01, https://www.thingiverse.com/thing:1001065.
I did not print the last one, but have no reason to believe there would be problems. Please let me know if you find otherwise.
The 2 parts fit together with the nimbles using the M3x40 bolts in the package.
The whole thing can be mounted on the front plate with 4 M3x10 bolts + washers. I like to use serrated lock washers too.
You can then easily (dis)mount the chimera/cyclops with 3 M3x8 bolts + washers and ditto.
No support, thanks to the 2-part solution. Printed part1 not at all perfectly with 0.15mm layers, but a little tlc made it fit ok. Please check whether the nimbles stand firm on the mounting plate.
Cutting the teflon tubes 11mm above the chimera/cyclops should set them flush against the nimble.
Edit (11/10/17) I couldn't find a way to mount the stepper motors without losing printing space, so I made a Nimble_Stepper_Mount, see
3-wheeled or Linear Railed Modular X-carriage (D-Bot Core_XY 3D Printer) by printingSome, https://www.thingiverse.com/thing:2206664
Edit (20-06-18) For a Berd-Air-pipe_mount to go with this thing look there too.
