Printrbot Simple
thingiverse
Tinkercad was used to create this item, which can be edited online at https://tinkercad.com/things/jf7WLLDGj2M (now featuring limit switches and an extruder motor). Inspired by Brook Drumm's release of STL files for Printrbot Simple parts (available here: http://printrbot.com/2013/07/04/sneak-peek-simple-files-for-hackerspaces/), the user imported these files into Tinkercad for simplified prototyping of modifications. However, the attached STL may not be very useful, unless you desire a scaled model of your printer.
With this file you will be able to print Printrbot Simple with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Printrbot Simple.
