Prusa MK4 Bling

While figuring out an X Axis homing problem (about which, more later), I printed a bunch of add-ons for the Prusa MK4, all from printables.com.

Stipulated: Using something other than black PETG and PETG-CF would make them more like bling.

The heatsink fan gets a scoop inlet to keep fingers and tools farther from the blades:

Prusa MK4 - fan cover - fan duct
Prusa MK4 – fan cover – fan duct

The small upward duct on the right side directs the exhaust air away from the platform. This is apparently critical for very high-temperature plastics like ABS and PC, but I did have one print fail due to excessively cold breezes on the platform.

I made three different ducts in case I break one:

Prusa MK4 - fan ducts on platform
Prusa MK4 – fan ducts on platform

The aluminum extrusions now have dust covers:

Prusa MK4 - Extrusion cover - front
Prusa MK4 – Extrusion cover – front

There’s also an angled heater cable connector cover, with a matching cover on the electronics box routing the cable rearward to dress it away from the hulking extruder cable:

Prusa MK4 - Extrusion cover - rear
Prusa MK4 – Extrusion cover – rear

And the Z axis stepper mounts have tidy dust covers:

Prusa MK4 - Z axis motor cover
Prusa MK4 – Z axis motor cover

None of which are necessary, but they’re all easy to print while thinking of other things.
