Cathal Garvey’s Mircolathe is a printable mini lathe made from MakerBot printable parts, ball bearings, a dremmel and other minor parts.

Microlathe by Cathal Garvey

Now, I don’t have a dremmel… but from problems are born solutions.  Everyone has an electric drill, right?  What if the back of the left printable piece had a flathead screwdriver shaped hollow?  You could pop a flathead screwdriver bit into the drill, slide the drill up to the microlathe, put the screwdriver bit into the hollow and turn it on.
