Roborock E4 - Bumper Kit (TPU)

thingiverse

I really love my new Roborock E4. The only thing that bothered me from day one: It's not exactly gentle when it comes to bumping into things. Especially with dark furniture since it seems to have some problems spotting darker objects. This already led to some really heavy scratches on the bot. So I created this bumper kit in Tinkercad which is mounted with double sided tape. For aesthetical reasons I recommend putting the tape on top of the print, so that the side that has been faced to the printbed is the visible side later. That's why all the STLs are mirrored. You'll need: 1 x Roborock_E4_Top.stl 1 x Roborock_E4_Side_left.stl 1 x Roborock_E4_Side_right.stl 2 x Roborock_E4_middle_bottom.stl 2 x Roborock_E4_middle_top.stl Optional: 1 x Roborock_E4_rear_left.stl 1 x Roborock_E4_rear_right.stl The optional parts are thinner (0,6 mm) than the other parts (2,0 mm), since they don't have to take any impacts. Their only job is to prevent scratches which can occure when the bot turns on the spot while being too close to a wall or any other object. It goes without saying, that these parts need to be printed in TPU or similar! Using stiff materials would be completely pointless.
