MPSM V2 fan shroud with blow ring

thingiverse

I wanted a fan shroud with superior part cooling, so I searched high and low until I couldn't find one that met my requirements. Therefore, I pulled out a ruler, opened OpenSCAD, and started designing from scratch! The original STL file and ver2 STL file are designed specifically for the stock 30mm fan. There is also a 30mm and 40mm variant of the ver3 version which smooths off corners and eliminates areas that previously caused issues. The ver2 files feature a redesigned ring, allowing them to print in an upright orientation without any supports required. This new design should provide optimal results. The ver3 files have rounded-off corners on the fan mount and improved support for 40mm fans. The 30mm variant can still be printed with no supports needed, but the overhang at the back of the 40mm variant will work better when supported. Keep in mind that this is an ongoing project, and I'll continue to update files as changes are made.
