Recently I got myself a mini-lathe.
Milling attachments for it can be purchased, but they are a bit pricey. So I decided to make one with a bit of help from 3d printer.
This is the simplest model I've come up with. It allows me to re-use parts of lathe itself. The model is a creative process, so it's a total mess.
Printed of PLA with 20% infill and 3 perimeters. It has just enough rigidity to slowly mill some steel. Not great, but good enough for occasional milling.
