FLEXTRUDER2 17: Dual drive remote direct extruder

I tried to mail them to be sure that the gears and flexible shaft was still available...

I had no response for a week now.

So this open source project has no sense if parts are not available... That's why I have started to re-design the thing with different parts:
* New worm gear, designed to be manufactured with plastic or metal... Flex3drive allows only plastic.

* New cable sleeve, for the new gear design

Now it becomes smaller and easier to print... See the screws? it's M2.5...

Now I'm in the process of ordering the parts: Flexible shafts with the new sleeve and worm gears.

Both Flex3drive and Zesty sell the gears + shaft for  $40 to $60... I should be able to be around $30... And less than $50 for the complete hardware kit.

So that this open-source project doesn't starve by drying of sources before it's really born.

And for people in need of a finished all-metal product, it's in the pipe...

For simplicity reason, I decided to rename this version: S is changed to 17 as it is the number of teeth...

Now there are already many gears available: 17, 18,25,41. So it seems logical to reference the model with the gear size...

So if I decide to create a commercial version, I can grind 19 to 23 and 26 to 40 tooth gears and change model every year pretending that the new one is definitely better...

The 18 gear 'G2' style gears are definitely interesting, as the shorter base will make a narrower extruder than the 17....

And just working on a 'proprietary' worm gear and flexible drive... I find the spare parts of Flexdrive or Zesty a bit on the expensive side, not to mention that they don't sell the worm gear alone.

So for people that can't recycle their already purchased shafts & worm gears, I might be able to supply soon.
