It is used to the first extruder,because China can't buy the upgrade package for the Ultimaker2:DSo you could use this and then just have to add a second tip/Bowden tube to have a dual extrusion um2+?

I see some problems with this design
- There does not seem to be any tension adjustment or manual filament release.
- The same side of the filament is gripped by both of the hobbed gears. This may unduly bend and deform that side, and prints with heavy retraction may fail.
- There are no filament guides. This design won't work well with flexible filaments.

I drew a picture for the first problem.
Thank you for reminding me for the second problem,I'll try to fix this problem.
(I am really sorry I can not understand the meaning of the second question clearly,because my English is not good) -

Thank you for your reminder.I'm ready straight axis.I chose a lot of shops, but also to buy a bad thing.That china board (most do) has the led/fan/ and head1/head2/bed molez connectors upside down. Remember to double check the +/- of the stuff you connect.
Also. 99% of the smooth rods from china have very bad quality. If you want good quality buy some misumi smooth shafts.

:DThis is the new processing of the machine casing -
Hello everybody，Long time didn't come back Let me introduce you to the latest progress.（My English is not very good, if you have said is wrong, please forgive me）Before that a set of problems appeared on the shell processing.So I back to the production.（Including nozzle，machine casing）Other components are assembled.I am waiting for CNC Machining center get the Nozzle processing job done.
Picture has not been able to upload，I will re upload the latest pictures later.

Not equal to the original works, and the price is more expensive:)But many Chinese merchants didn't shop on ebay

New Extruder for ultimaker2+

Do you mean my last point? What I am saying is that a flexible TPU filament such as NinjaFlex will not neatly feed into the extruder, then from the first hobbed gear to the second one, and then out to the bowden tube, if you do not put a channel or some tubing in to control where it goes.
I think what you said makes sense，TPU filament should be a problem.I prepare for a test and fix my extruder:P
