Gear bearing filament roller for CraftBot

I was never 100% happy with CraftBot's original thin filament holder, therefore I designed a simple, yet elegant gear bearings for smoother rotation.

Most of the filament rolls have 56mm hole diameter and 75/90mm width, so I target them.

I started with customizing Emmett's pre-assembled Gear Bearing design using the following options:
tol = 0.2
number_of_teeth_on_planets = 5
number_of_planets = 5
w = 16.5
nTwist = 1
P = 45
T = 10
D = 56
