Instructions

What you need

a printed template (schablone.stl)
3mm foam rubber (like this http://www.conrad.de/ce/de/product/230043/MOOSGUMMI-ZUSCHNITT-SELBSTKLE-300X200X3/SHOP_AREA_32472&promotionareaSearchDetail=005
M3 Screws (longer than you actually have :D )
4,3x15mm washer
25mm and 4mm hollow puncher

Cut out two 42x42mm pieces of foam rubber for each stepper you want to silence.
Put a piece into the template and push the hollow puncher through the holes (do this on a old wooden plate !!!)
Now you just have to install the Plates like shown on the pictures :)

Have fun to print through the whole night without disturbing sleeping neighbours ;)
