CNC parts (finally making useful stuff)

Here are some pictures of a case that I machined from SINTRA (PVC sheet). It is for my Raspberry Pi. I designed the part in Sketchup, then used an export plugin to send it as an STL file to CamBam, where I created the toolpaths.

I am really pleased with how the SINTRA machined, though it meant standing over the work table with a vacuum during the entire cut. A vacuum attachment would alleviate this...
