QU-BD Fan Gasket

Status: work in progress...

I have not tested it yet. I will try v2 the next time I disassemble my extruder. If you get there first and have feedback I'd love to hear it. i have printed v2 and think it is a little flimsy. I will think about widening it, or making it slightly thicker. (I want to stay below 2mm). I'll update this intro as I progress.

Description:

This is intended to be a gasket between the fan and heat sink on the qu-bd extruder. I have broken 3 fans in the removal/reattach process. I believe the bolts are putting too much stress on the plastic fan against the heat sink fins.

In an attempt to spread this force I cut my first gasket from a scrap print and it has been working great. No more cracked fans since. This is intended to be a replacement for that first gasket. I added a shroud to limit the air flow to the upper part of the heat sink. (I'll see if this increases noise, I don't expect any performance change...)

The _v2 increased the bolt holes from 3mm to 4mm.
