The Nimble is so flexible and easy to use, partly because of the unique shape and partly because it uses an adapter (or mount as some call them) system to attach them to a printer.
For Version 3, AKA the flex, we have increased the mounting flexibility even more. There are still three mounting screws, but you can decide the direction of the drive cable.
There are Flex adapter design resources available.
Also, check out the collection of Flex mounts available on Thingiverse.
For Version 2 the mounting points for the Nimble and the Sidewinder now identical, so in most cases an adapter for the Nimble V2 can now also be used for the Sidewinder.
There are a lot of adapters already out there, some designed by us, some by others. Some good, some experimental. So use your own judgment and be careful out there. There is no guarantee or warranty for any of these designs.
If you are using a Creality type print head, check out the special page for more details on how to mount a Nimble on the Ender3, CR-10 and the like.
