Anet A8 Z-Motor position meter

Have you ever wondered if your Z-Motors are properly positioned when going to home position? This is a very simple design but very useful to be sure that your printer places the extruder where it should be. Just have a look to your "meter" and you will see how accurate is every time it goes home.

My recommended settings:
0.2mm/layer
20mm/s
100% infill

Print two of these and put them on Z-Motor couplers. It takes about 7 minutes each.

Please, post a picture if you make this thing. Thank you!!
