200mm Fan Front for Fractal Node 304

A remix of the previous two models with the following changes:

• The fan is mounted to the back of the panel via heat-set inserts. 
• Magnetically attached fan cover. 
• Holes for a reset button and the original power LED.
• An excessive amount of zip-tie points.
• STEP files for easier customization. 

Required hardware:

• 22 x M3 heat set inserts (4 mm length; OD 4.3-5 mm) (the M3 X D5.0 X L4.0 option here).
• 22 x M3x6 mm socket/button/flat head screws. 
• 16 x 6x2.6 mm magnets.
• Buttons that fit ⌀16 mm and ⌀12 mm mounting holes (I used this and this one).

Printing:

• Set initial layer height to 0.20 mm. Otherwise slicing may not produce a continuous surface on the first layer around the magnet holes.
• Print in whatever material you want, but keep in mind that PETG may warp a lot due to the large contact area with the print bed.
• I printed with Polyterra PLA (Army Blue), 0.6 nozzle and 0.45 layer height.

For the fan cover, open the part in your slicer and add a cylinder modifier with diameter 198 mm and height 10 mm. Center it and set the following overrides:

• Remove top and bottom layers.
• Set infill/wall overlap to 0.
• Set maximum length of infill anchor to 0.
• Set Infill/Wall overlap to 0 (can't find the equivalent in PrusaSlicer). 
• Play with the other infill settings until you are satisfied (I used 30% rectilinear).
