I rebuilt the extruder on my Delta #RepRap again

I rebuilt the extruder on my Delta #RepRap again. Trying different things to find something that works for me. This is a cable-laced short bowden tube with no 'real' connectors. Quick and dirty, but it seems to be working well so far.

In album Repaired stubby bowden tube

The cable lacing is where the hold-it-all-together should happen. This is with Spectra fishing line. Same as I used for the drive-line. Low stretch. Should keep the two halves from being pushed apart.

Boom! Wonderful printing all of a sudden.

Installed. The idea is to balance the weight of the motor over the effector so the printer doesn’t have to sling all that weight around.

I used some self vulcanizing rubber tape to try to get some traction on the tube. It should also stiffen up the joints a bit so there is less flex at either end and more in the middle.

This is the prior iteration. The nylon kept wanting to stretch so I kept twisting the extruder around to tighten up the cable lacing. 2.5 full turns here! The nylon also dug into the plastic a bit as well.
