Similiar Firmare for Ender 3 available?

[okaufmann]

Hi Guys

I got myself an old supposedly defective Ender 3 (The oldest model) as secondary Printer, but I got it perfectly working again.
As I love what Jyers did for my primary Ender 3 V2 I asked my if there is a similar firmware for this old printer?

Especially the Manual Mesh/BL-Touch Meshing function is so handy and to level it manually is so annoying...

(Btw: it got a new Original Creality Motherboard v4.2.7 for the silent drivers)

Really appreciate any tips ✌️
