Printrbot Play Shield with with view for filament.

This is to help to prevent jamming while trying to figure out the best settings for flexibles on the Alu V2. It prevents jamming by allowing you to view the filament while you are tuning your print settings, pausing or quitting the print before it jams severely allowing you to recover and immediately resume printing after adjusting your settings (generally just slowing it down). Otherwise you may need to take off the shield and fix, then reattach the shield, which is just a waste of time.

I might add a fan nozzle in the future, but wanted to get flexibles working first. This version (compared to pictured version) has a bit more support to the bottom fan, as printing it the same way as the original printrbot design (as pictured) has no benefit.

The triangle is perfect for me, though some may want access to both allen bolts. It should be easy for people modify the design, but I've included the solidworks file as well.
