Hi...I was experimenting with some cases and bumpers to protect LaunchPads as they float around on a desk or in a box of parts. The regular LaunchPad bumper is based on some existing concepts, which I used to create a new design in Autodesk Inventor. The 5529 bumper-case is the same basic idea but with a snap-on lid to protect those easily-bent pins on the top. I just moved to Dallas and need to dig out my 3D printer (among other things) in order to refine the designs a little, but should be able to post some STLs in here soon if there's interest.
