Anet A6 with a pen

thingiverse

I'm using my Anet to mark out some aluminium sheet. I was already using RichieK's great filament swapper solution so it was an easy adaption to reprint the bottom bracket with a pencil sized clip. I have also printed a 10mm Z top adjustment that will slot on the left hand side of the printer's X axis bracket. This means when it autohomes, the underside of the bracket will hit the zstop early, stopping the printer with the extruder some 10mm above the print bed so only the pen touches the surface.
