The simplest possible e liquid mixer/steeper I could come up with.
Needs a 3-6v geared motor and 2 m3 bolts and nuts
It can easily spin a 250ml bottle when powered via a power bank, and the holder can easily be altered for other sizes as well.
I personally tie the bottle to the holder with a couple zip ties daisy chained, at it's been spinning for 3 hours without any issue.
If you want to be able to vary the RPM, get a step down converter, I personally hook it up directly to a 5v powerbank and it spins at aroun 80-100 RPM with a full 250ml bottle.

Also, it would probably look nicer with a clamp instead of tape, but I was excited to get it spinning.
