Description

This thing has moved to Youmagine youmagine.com/users/jensa so I don't also get sued by Stratasys...

Less material - more retraction

Calibration of 3D printers. Due to it's shape it is well suited to test how good a FDM-type 3D printer is at stopping the flow of plastic between each of the four pillars. This is normally done using "retraction" where the plastic filament is pulled back some mm into the tube while the print head moves.

What is it used for?

Instructions

Made this quickly after doing a couple tests, only to realize that MINIFACTURE (http://www.thingiverse.com/MINIFACTURE) had already done it. Duhhh. Oh well. Good boolean excersise and here's a Rhino file to go with it as well.

The enclosed image was my first print so I still have some milage to cover in terms of calibration, but I'm quite happy with how it turned out
