Here's a video of a delta that someone has built using an extruder on a 4th tower, enabled by the recent addition of support for more than 3 towers in RepRapFirmware. Notice how the height of the extruder adapts not only to the Z height of the extruder but also to the XY position.

Disclosure: I design Duet electronics and work on RepRapFirmware, [duet3d.com].

There is no new idea in the world!

I thought shoter Bowden tube removes many problems caused by excessive bending of the tube during printing.

I added the fourth axis to install the extruder on my Fisher last year.
- Two smooth rods
- Counter weight
- Extra printed parts
- Two pulleys
- Two cylinderical bearings

I haven't finished it though.
