Bowden Tube Conversion for Gregs or Wades Extruder, Threaded Fittings. by inthebay Nov 25, 2013

Description

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. It has a hole mount that fits Magma hot ends that were reccommended with the Makerfarm Prusa i3.

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:

mcmaster.com/#5449k173/=piy2zb - Push Tube Fittings
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"

Cheers!

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.

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.

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