I needed a 12v fan for my Biqu H2 (for reasons), and 35mm ones weren't locally available. I also wanted it to look a bit cool (at an angle) and subsequently decided to put an RGB mount on it (because fan RGB)…
The fan is angled up and to one side for a bit of interest. The lightbar version has a pair of mounting holes 25mm apart for whatever you might need there.
BOM for mounting to a Biqu H2 using a “BIQU H2 Ender 3 Pro Carriage Mount for MAD system”:
2x M3 x 15mm
4x M3 x “depth of your fan+5mm” (The non lightbar version should use M3 self tapping screws as the holes are a little loose for machine screws, but the lightbar version can use machine screws)
2x M2.5 self tapping screws for lightbar version
