Roomba 700 series front wheel / castor

thingiverse

This is a printable front wheel for Roomba 700 series, possibly compatible with other models but guarantee not provided. The wheel utilizes two 4mm x 13mm x 5mm bearings and reuses the original axle. My print in ABS employed pillar supports for the bearing indent. The part is still printing, but post-processing will likely involve heating the part and bearings to facilitate assembly due to anticipated tight fit tolerances. I decided to incorporate bearings into this design to compensate for the absence of a soft tread, hoping it will improve rolling efficiency and durability. Since I haven't tested it yet, its effectiveness remains unknown; I'll update once printing is complete.
