I needed to bench some coaxial motor setups, so I built this thing.
All you need is some M3x10mm screws, a 8mm shaft (can be a wood dowel or carbon tube), 16mm carbon tubes, Z608 bearings (2) and motor mount.
I use some TAROT RC 16mm clamps and custom carbon plates, but you can use any motor mounts that fits on 16mm tubes.
Drill the carbon tubes with 2.5 or 3/32 bit when in place (screws will lock in there).
This bench is made to be used on any scale that is 5 to 10cm high. The main mount is adjustable to height to get a good reading.
Printable motor mounts:
You can use support for the main plate, but it's only for mounting slots, theses do not need to be accurate.
Everything else does not need any.
PRINT ALL THE PARTS FLAT! The main support needs to rest on it's "back" (largest flat surface on the build plate). The block/pivot needs to be on it's side. Support is suggested, but you can also just heat-up the block a bit before fitting the tubes (tighter fit, better readings).
