Paper Cutter Tool for Disk Decoder Ring (Q62775)

The idea here is a tool that can be used to cut shapes out of paper with interchanglable parts. The specific example this is made for is the Disk Decoder Ring ( http://www.thingiverse.com/thing:17582 ). For the blank disk option you need to cut the disk out of paper and then cut a hole out of it. This should do it perfectly.
