What a irobot roomba front caster wheel is
A front caster wheel for iRobot Roomba 500, 600, 700 and 800 series robots, about 25 mm across and 12 mm wide, turning on the original 3 mm axle. The hub has a 3.2 mm bore for 0.2 mm clearance and a 2 mm groove for a separate TPU tyre. Print the hub flat in PETG and the tyre in TPU.
The Roomba i and j series use a smaller caster, so this wheel will not fit them. Open the ready-made caster free in SpeakCAD, change its diameter in the chat or the viewer, then download the STL.
