Fan Holder 80mm for ZRIB 5.x (Zonestar P802N, P802NA)

thingiverse

I adapted the fan holder from user "dark307" to work with the new ZRIB 5.x boards which support the step stick stepper drivers. The two main changes are 9mm additional clearance between the ZRIB board and the holder to accomodate for taller heatsinks on the step sticks and lowering the fan by 9.5mm to better cover the area of the board, where the step sticks are located. On the photos, you can clearly see that the clearance allows stepper drivers like the silent step sticks with taller heat sinks without a problem. The lowering of the fan also helps with Z homing since it adds additional clearance between the X-Axis motor and the top of the fan. I use an Anycubic Ultrabase on my printer, which raises the Z homing position by 3.8mm, which I indicated with my calipers. However, even without the Ultrabase, there is still enough clearance for the fan holder.
