I'm working on getting the Cheap Chinese Laser working again.

I like designing utilitarian objects. My motivation to fix the laser is so I can make a holder for my pens at work. Aside from hacking together useful things via CNC machines, I like hacking in the kitchen and am known for my award winning experimental pies. Who needs raspberry when you could have custard instead? I'm a temporary resident of Hyattsville, so if you need a lift in that direction, hit me up. BTW, ladies, he's single.

STL file of key fob is available as a zip file here: File:HacDC-tag.zip. Dimensions in millimeters: 25 wide, 40 tall, 2.5 thick. The above code causes Openscad to hang, so the STL was created using the surface command and a single full length image. Image could use some tweeking at the pixel level.
