Ultimaker Quick Connect Shim

Ultimaker Quick Connect Shim by LawrenceJohnston May 11, 2012

Description

When doing retraction with the Ultimaker the quick connect on the extruder allows quite a bit of play.

This shim fits on the quick connect and essentially eliminates this play.

See posts such as this one: groups.google.com/d/msg/ultimaker/fNgHD9W6bkI/D5F2PjhWSI8J

This thing was created using the Object Oriented Mechanics Library (OOML). See iearobotics.com/oomlwiki/doku.php?id=start for details.

This solved so many stringing problems, great work! I had to really pry the tube up to get this in there, and I put some tape around it just to be sure it wouldn't go flying out. Works great!

My shim fell off almost immediately and I am now giving the one with a zip tie a chance instead. http://www.thingiverse.com/thi...

Only just found this why does not ultimaker give you this part or have it recommended! Yet to see if fixes my issue. My retraction stops the filament extruding for a short period at random so skips a layer thus failing to print next layer.

Instructions

Print shim.
Pull the bowden tube up from the extruder until a space is formed between the pieces of the quick connect.
Insert the clip around the inner piece of the quick connect (see picture). This prevents it from pulling back down into the outer piece during retraction.

If you later want to remove the bowden from the quick connect you must first remove the shim.

Love it! I did this a while back with some plastic shim stock. This is 'key' to getting retraction working.

Great Job!
