Honestly this is ghetto. For roll up, try a through hole servo, and put it inside the top box on the shaft.
But at this juncture, its just as cost effective to buy some chink ones from amazon.
Yeah, sometimes you build something just to do it. Sometimes you don't know better.
For a "roll up" set I totally agree. Just need to put something on it to allow it to operate manually still.
Manually? That's what the slaves are for.
The west made that mistake once.. And is doing it again with Criminal Illegal Aliens.
I would rather build a house from scratch on my own than have the "slaves".
