Simple carriage for Sapphire Plus (SP-5) gen2, maybe works to gen1 and gen3 and also to sp-3, I can tell, I own only one printer.

Offset of BLtooth 22.4mm. This is super low level funduct, only 1.5mm from nozzle tip.

I include only STEP file, becomes its much easy to edit if need and remix.

without printed parts you only need extra

m3x25mm x6 screws for fans

m3x20mm x2 and m3x10mm x2 for fanduct and beck mount

m4x15mm x2 for belt tension.

and m3x10 can use original for mount linear rail and extruder
