This is a bowden tube conversion I designed with the help of Stu_Dkn's bowden extruder mount (Now replaced with my own iteration for direct mounting) for Gregs or Wades extruder. The two key parts are the extruder bracket and the x carriage mount. The extruder bracket can be mounted anywhere that facilitates a short tube run, I personally mounted it to the left of my LCD by drilling two holes into the frame. Utilizes standard groove mount sizing.

This design takes two 1/8" Pipe thread fittings and whatever size tube you choose to use for your bowden tube. I used these parts:

http://www.mcmaster.com/#52335k53/=piy3p1 - 3mm ID tubing

This tubing was a bit snug on true 3mm filament, but my local supplier's filament is undersize. You may wish to use tube with 1/8" ID to give some more wiggle room.

Good luck, and enjoy the fast vibration free printing, I saw an instant 50% increase in movement speed, with faster printing to come with more tuning!

The fit is tight on the threaded fitting, by the way, if you do not have a tap (common in most sets) you can chamfer out the piece with a razor.

EDIT 1: I have updated the design files extensively, they now contain a family table and adjusted files to accomodate 1/8"NPT, 1/4" NPT, and I am currently experimenting with a straight tube to tube connector that may work, hence why it is tagged as "Experimental"

Added M5x0.8mm threaded fitting version for use with 1.75mm filament bowden setups. Experimental, am in the process of setting up on my printer at the moment.

Nice idea
Your printer looks great do you have the dxf file?

Nice retro fit! Yes, you Could have reprinted a whole new version but WHY? your 90% their already. good job!

Nice design! Is it printing better than when the extruder is mounted on the axis? I thing there is some tweaking involved in the retraction of the filament or is that not needed.
If it works well, i think by the time i'm going to try to make a dual-extruder remix if you don't mined.

Nice, just happened to come across this and couldn't pass it up, I haven't used a bowden before and wasn't planning it it, but I got an all metal hotend assembled for super cheap and figured this would be a good time to start. I am currently using a Greg's wade with a jhead hotend, so there should be any issues and I should be able to use the same step calls when I calibrated. This makes it really easy to convert. Looking forward to it. Nice job

It look like the parts are mis-labled. On the extruder side, the hole sizes are mixed up. The hot end side has the same size hole for all the sizes.

Nice... what speed are you using to print with this set up?

I've had it up to 150mm/sec, but I started having vibratory issues with my frame, as it had loosened up over time. Comfortably printing at 100mm/sec now.
