Gearbox add-on. Lever cover. First, you need to cut the material in accordance with the dimensions in the drawing. Add 10mm to the side as shown by the dashed line

Sew with thread. You should get this cone

Print out the ring “Ring_handle.STL”. See file for printing below. Pass the handle into the sewn cover and press the ring on top. If it dangles, use glue. I got it very tight and holds great without additional glue fixation

Print the cover “Onlay.STL” and screw it with spirally grooved nail 2.5x13 to the gearbox. There are already holes for this!

Screw the handle with the cover onto the lever

Print out the “Ring.STL” ring. Fasten the ring from above with 10 screws with 2.5x13 self-tapping screws, carefully tucking the bottom edge of the cover under the ring. It should look like this. Good luck!

Details for printing gearbox supplement

Today I made a handbrake. Now i can drift. Connected to arduino Leonardo gearbox

I think it's time to introduce the third axle (traction loss). Convert 2DOF to 3 DOF

What angle would you recommend for traction loss?

Thanks for the advice. I thought about the same I understand that the load on the motor will be less than that of other motors. I have a BLDC 150W motor, through the gearbox I think that's enough

Improved gear knob. It is larger and feels better in the hand

Here's some more gearbox race video

How would you like to use an electronic vernier caliper instead of potentiometers in linear drives? There is, for example, a caliper with a length of 300 mm. The measuring principle, as I understand it, is based on capacity

After a little thought, I decided not to make the third axis (3DOF), but immediately upgrade the installation to 6DOF. I am opening a new thread, where I will show the transformation of a moving platform from 2DOF to 6DOF.

A little more video of how lateral overload works

Crash car or traffic accident
Plastic could not stand high speeds

An adapter for a shaft with a diameter of 8 with a flat (red arrow in the picture) for a diameter of 14 with a key is included with the gearbox

As you can see in the photo below, on the inner diameter of 8 flat (red arrow in the figure), it is almost worn out. After a while, the connection between the motor and the gearbox would be interrupted

Best used without an adapter. Select the appropriate shaft on the motor to connect directly to the gearbox

That looks a bit scary. have you considered making the base longer both back to front and side to side, that will help stop the rig from jumping of the ground . that weakens the plastic joint brackets that hold the rig together or maybe switch to steel brackets
