My oven is old. Made by Sears some time in the 1950's we think. One of the knobs that controls the light and fan is missing and the other is melted. I can't find replacement parts that fit. So I decided to print them.

This was designed to print on a MakerBot. I sliced and printed using ReplicatorG 0017 and only made a few tweaks specific to the bot I was using - nothing too drastic. The spindle hole comes out a little undersized. I'm not sure if that's something that can be tweaked in Skeinforge but you may need to enlarge the hole a bit.
