Motorized Lemming Blocker

Off course you need someone to safeguard your printer while you're away, and no one does the job better than a heroic Lemming Blocker!

Fun and a bit challenging build, as I did not make any step-by-step instructions for this. However I think you get a good idea by watching this video:

WARNING/DISCLAIMER: 

1: Motor tends to get hot after long time in use, take care.

2: Handle the 220v wiring properly or let someone else do so.

BOM:

1x Microwave turntable motor

M2 and M3 screws

1, 1,5 and 2mm hard steel rods (get them at hobby/RC stores)

Small washer (like ID 2mm) between head & body, lowering noise

Filament (I used PETG all over)

Optional (I think): 5mm magnets and washer for the magnet brake. I dont really think it's needed anymore with the new steel rod sliders with low friction.

Optional: Some plastic friendly grease for the gears/slider might be a good idea to lower noise further. Will soon try this out myself.

Sure hope someone will build it, and would love to see the result. Good luck!
