Corsair H150 AIO custom logo pump cover.

The Corsair H150 AIO cooler has a cosmetic pump cover that displays the Corsair logo and it is attached magnetically so that it can be rotated in order to let the logo be upright with any pump orientation. This also works with the H55 and H100 models, which share the same heatsink/pump assembly.

You can unscrew the four screws on the back of this cover to take it apart and i thought i could recreate it to print my own logo.

The dimensions I designed take into account my own printer tolerances. I went through some trial-and error, you might need to adjust the diameters of the little pillars the screws attach to, but it's a small part and prints in minutes, so you can really fine-tune it if you want.

There are two ways you can have the RGB light shine through your logo: you can either print this part flat, in white/translucent plastic and paint the negative space in black to block the light, or you can include your logo in the design with your software of choice (I used F360 so I included a fully modifiable .step file) then print the face in black plastic and the rest of the cover in white, after a few solid layers.

The first option is best for detail, but you'll have to resort to some kind of screen printing if you want to achieve factory-level precision and light blackout. The latter takes a little trial and error, and it requires you to print the logo face-down, which depending on the gauge of your printer, nozzle, bed calibration, etc.. it might lose some detail. YMMV.

To print my own design I first extruded the text -1 mm into the surface of the part, then I printed it face down on my Bambu Labs P1S with a .6 mm nozzle and 0.18 mm layer height, no supports, 100% concentric infill (for maximum light blockage, some kind of infill pattern might look good if light shines through the part though).

I added an automatic pause at layer 4 and manually switched filaments from black ABS to white, as i do not own an AMS. AMS users might achieve good results by printing this upright, tilted and supported on its back side to maximise print detail but increasing waste and print time.
