K2 Plus Heater Clip-on shield diverter diffuser

Easy Snap-On air diverter and shield for the K2 Plus heater to direct it away from the 3D print area.

Looking to the few designs out there I did not like the full implementation.

1 - The air should be directed down - away from the thermistor that is above the heater.

2 - It should be minimally invasive and easy to install/remove - no screws, tape, glue, magnets.

3 - It should take advantage of the full space between the bed and the back of the K2 Plus (depth)

4 - Designed as a single purpose and not intergraded with the air filtering system. (I have an external venting system, so no use for additional carbon filters, etc)

My Design utilizes the vertical slots in the exhaust vents to maximize the air flow from the heater and is minimally invasive to the exhaust system.

I found with the engineering, that using the vent slots on the heater grip itself were not reliable or strong enough to stay in place. The slits themselves are also angled upwards making it even more difficult to design a snap-on that would stay in place. In addition, there is a frame behind the grill preventing the mounting tabs from being close the edge. This prevented the design of the mounting system that was not invasive to the air flow of the heater.

I printed mine with ABS and it holds up pretty well. One on of my proto type testing runs, the outside air was 0degC, and I must have the little heater that could in my K2... the housing did get some heat warp, but still fully functional and sits flush to the fan. You may even want to think about printing in PC. I have not tested that yet, but will soon.. For sure, you will want to use a High Temp filament; PLA or PETG will not work here
