Last year, I bought a 3D printer, and found myself having to make many small objects sequentially for customers' production runs. So, I had to come up with a way to clear the build plate. So, I did! It's been a year, so I'm going to open the design.
It needs to be cheap, easy to build, and adaptable to many printer types. And ideally quieter than the prototype since the idea is to print things overnight and I don't think everyone has their printers in a closet!
