Husqvarna Automower 230 ACX Replacement Tire

cults3d

The tires of my Automower where worn and the mower lost traction. I wanted to try to print my own replacements (because I can ...). They have come out really well, but the proof is in the pudding, field test started May 15th, so far so good. To able to print these on my Ender 3 I had to design them in segments (3x 120 degrees). Three bottom and three top segments that click together around the wheel. The inside segments are the same, the outside segments are the same except for a locator pin on one of them to prevent the wheel from turning inside the assembled tire. Radially the segments are locked up completely, axially the outside segments are held by the wheel cover and the inside segments are held by a screw. I printed with PLA, 0.3 mm layer height and 20% infill. I do not know how long the PLA will endure in the outside environment (ABS would be more suitable?). Unfortunately the profile is not solid either, it may wear quickly.
