75mm Fan Conversion for Creality Space Pi Filament Dryer

The original fan failed (started making an awful noise, clearly was going to stop working soon).  I couldn't seem to find an exact replacement online, so I bought a 75 x 75 x 30 mm blower (with ball bearings) that looked like it would fit.  This conversion kit creates a mount for the fan and ducting to bring the air to the heater.  The new fan works well (temp came up in the dryer very quickly during my first test), and it is quieter than the original fan when it was new!

You will need:

• 75mm blower fan, 12V, 300 mA (Amazon: https://www.amazon.ca/dp/B087TRYH9M?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1), including mounting screws and nuts
• (2) M3x10 socket head screws
• (3) M3x6 or M3x8 socket head screws
• The original fan mounting screws (re-used to attach the new mount to the same posts)

There are a few places online that describe how to take apart the Creality Space Pi.  It's not easy though…   https://wiki.creality.com/en/3d-printer-accessories/replace-dryer-fan

I printed these parts with PC filament to ensure they can handle the heat.  I used standard settings (0.2mm layers, 2 perimeters, gyroid infill 15%, snug supports - painted on, see .3mf files).  The lid is thin and needed a brim as well as some supports.

The photos are an earlier iteration of the design although only small tweaks were done to improve the fit.
