Mova LiDAX Ultra Weight Box

Just a small box that mounts in the handle of the Mova LiDAX Ultra series robot mower. It may also fit in the Dreame A2, but I do not have one of those to test. The fit is a little tight, so you may have to scale if you have difficulty mounting the box.

I made this because of how aggressive the treads are on the wheels. On flat surfaces, or areas with thin grass, it doesn't have much traction. I also have a bit of a sloped lawn, so the extra traction helps. The box is printed and mounted in the handle, then some weight can be placed in the box. (Or if you're being cheeky and having fun, any small object and use it like an RC car to deliver elsewhere).

This weight helps put more force on the wheels and increase traction. Just be careful, it may cause the wheels to dig in on softer/wet soil and may damage grass. PETG or better, since it'll be out in the sun and possibly under force and PLA may flow.

There's 3 versions;

The standard one (pictured) is short enough to slide through the slot between the mower shell and handle, then slide down into the hole. This is the easiest to mount, but holds the smallest amount. (In the image I have adjustable weights at 0.5lb apiece, 4 fit this box adding 2lb total). Also allows for quick removal.

The one labeled Deep adds an extra 25mm to the bottom, allowing more weight to be put in, but still a safe height off the ground. However, this one requires flipping the mower over and removing the 4 screws holding the handle on, sliding the box in, and remounting. You can then add weights via the gap on the back of the mower. Your standard issue middle-ground difficulty. Work a little more, get a little more. Suggested if you never use the handle, but want the ease of access.

Finally, the Max one not only adds the 25mm on the bottom, but it also extends an extra 40mm up into the shell of the robot, effectively doubling the capacity. This one increases the difficulty all around, printing requires supports (the other two do not), install requires not only removing the handle, but also pre-filling the weight box, and mounting it from underneath. This is because it extends into the shell, covering the gap in the back, so you cannot add weight after mounted. I suggest placing the mower on a table with the back near the edge so you can access the screws underneath (or something like a park bench where you can run a screwdriver between the slats). Higher difficulty, but you get maximum capacity. Pretty much permanent attachment.
