Parametric Lego Mindstorms Omniwheel.
The OmniwheelSolid can be printed without any support structures.
8x Lego Axle 3L (length=23 mm, PartNr 4519)
Also added are the files with name containing the word "_printable". These files have been slightly modified so that my 3D printer prints them more accurately.
The base of the omniwheel has been printed in ABS. The barrels have been printed in Ninjaflex, which works quite well in preventing the slipping of the barrels on smooth surfaces.
