Head
Mellow NF-BMG-WIND V6 Dual Drive BMG Extruder - "right" orientation
high quality M3x5x5 brass insert to plug into plastics. Don't ask me for the nut version of printed parts. Brass inserts are far better than nuts, specially in PETG. Or tri budget variant M3x5x5 brass insers
high quality M3x5x7 brass insert or you can use M3x5x5 instead, but longer are better.
M3x4x3 brass inserts It is needed for BLtouch mount and Xmin sensor.
M2x3.2x3 brass insert
BL touch. I recommend original here. I was try few clones, it was lost money due to instability of measurement.

2pcs MGN12 rail with MGN12H block for Y axis. Lenght is same as your Y 3030 profile ((for standard 300x300x300 it is 410mm)
I recommend this high quality GT2 pulles. 2pcs without teeth 6pcs with teeth. Far better than china standart, but with 10mm width, this design accept this one or standart chep one.
2pcs GT2 Belt Pulley 20 teeth
M3 hammer nuts for 3030 profile to mount MGN12 Y rails
Frame
4pcs 3-way corner for 3030 profile.. It is needed, because my motor holders and idler holders are not compatible with inner "L" corners.
