Is there anyone who already has a bracket or something to put a reverse bowden on the sv07plus.  
I’m planning on building a color changer and then i would need a bowden tube straight to the filament feed on the print head.

Did you ever try to do this? Noticed that you hadn’t received any responses.

I’m thinking of attaching a tube holder to the sunken nut on the base of the spool holder. Not sure if I can also include the filament runout sensor, but want to try.

Fun stuff

Looking at the CAD model of the extruder I don’t see a “good” way to align a bowden and maintain accurate location.

The “copper sleeve” on the top is press fit. You could thread the inside M2.5, put a bolt in it and pull it. That would leave a 5.3mm hole that could be drilled (8.5mm or letter R) and tapped M10 to accept a standard push through fitting. I would drill the pilot hole below the fitting to 4.1mm about 10mm to allow the PTFE tube to be inserted farther to avoid the filament catching on a sharp edge below the fitting.

Pro Tip - Countersink your hole before threading. Easier to start your tap and looks neater.
