Still in an early stage of development, so it's not perfect, but it is usable.
This is a simple bumper/header/proto for the Fretronics LeoStick (http://www.freetronics.com/products/leostick) using advanced 3d printed header pin technology: http://www.thingiverse.com/thing:225255.
Create your own unique LeoStick Headers... just add pins (hopefully better than in the preview... that was a tough night).
I still want to make it cover more of the base of the LeoStick, and increase the clearance of the middle so it can slide past the "big pins in the middle" (scuse the ignorance... I'm not that far allong yet), add pin holes to the proto area in the middle (with above mentioned clearance)... then I'll start on attachments.
