so help me out here....what screws and nuts are you supposed to use with this???

qty 2, M4x15 for mounting to the bearing block. Head type doesn't matter but size needs to be exact
qty 2, button head M3x12 (only one needs to be button head for clearance, length can vary between 12 - 20 or so)
qty 2, M3 lock nut
qty 1, M4x25 (for the fan)
qty 1, M4 lock nut

So you have a little leeway on some. Honestly not sure what I used to secure the fan, just something I had nearby but it's roughly 4x25

This is simple design is awesome! Extremely easy to install and the "open" M4 Screw design seems to reduce vibrations to the Extruder! Thank you very much!

Works great - thanks for the effort!

Love the super simple design! Bolted right up to the unused threadserts in the bottom of the extruder carriage in the v2.1 printer.
