Tevo Tarantula 3 wheels bed support

Since I have received my printer, I have always thought the 4 wheels/4 level points bed was a pretty bad design from a mechanical point of view.
After checking a few designs, I have taken inspiration from various 3 wheels carriages and have decided to design my own 3 wheels/3 level points bed support.

This bed support is a bit longer than the original, but you can still use the full bed size (small bed) if you set your printer structure correctly (move the arch backwards by ~15mm)

To use this bed support, you'll need to tweak your printing bed to put an intermediate support point between 2 of the original 4 points.
On mine, I did that by adding a 3 holes steel spacer (more details to come)

For those looking for an even stiffer design, you should take a look at my latest bed support :
