Tired of your Yuka doing wheelies instead of mowing your hills?
Try an anti-wheelie ballast hat. I filled mine with rocks, some sand but eventually I'll epoxy something in to make it nice.
There are M8 holes (6.8mm) on the sides that can be threaded to add some grub-screws but I haven't needed them so far.
Material: I used carbon PETG but ASA would probably do ok… there's a heat sink on the top of the machine that may get pretty warm, would use caution with anything not highish temp.
Disclaimer: This was made from a 3D scan of my Yuka's ballast, given it's cast iron they may differ from weight to weight. I added the STEP file if you'd like to customize it for yours. Also this is putting rocks on your robot, use caution.
