Our first project on thingiverse.com is now available.
If you have purchased an Infitary Printer, like this....
Maybe you could damage your extruder, sooner or later.
We made this project to perform a right extruder model, of makerbot spring-loaded extruder, for our printer starting from a previous project posted on thingiverse.com from Jens Behrens.
All references to the project can be found to this link.
