Pcb and eagle files for hmeyer [http://www.thingiverse.com/hmeyer] cheap magnetic endstop [http://www.thingiverse.com/thing:24189] It's designed to fit Mendel Prusa's standard endstop holders so it should work with most reprap printable holders. Instructions In Eagle, display only bottom, pads and dimension layers. File->Print select "black" option, print it with a laser printer on magazine's paper (the best one are the free advertising magazines and catalogues, doesn't matter if they are full of ink :) then lay the printed circuit on a copper clad, fix it with tape, set your flatiron to max temp and apply pressure for 10-15 mins till it starts to smell burnt. Let it cool down completely, remove the paper, the toner rapresenting the circuit should now be on the copper. Etch it, cut accordingly to dimension layer, drill holes, place components, solder them, now the endstop is ready. Set a piece of neodimium as endstop trigger, wire it to your electronic and enjoy!
