Complete (and Simplified) Qidi Plus 4 Part Cooling Fan housing and shroud for Beacon Rev H bed leveling sensor.

im removing the old version since it makes no sense to have a complicated mess when the new one is so simple

Iteration is always good, I've simplified it even more and have improved cooling. so this is the final

I also have a solution to the pinout, Using female microfit molex terminal crimps on a standard 1x4 molex with some effort, or sanding/cutting off the front you should be able to push the pins through an extra 2 mm. the microfit are smaller and thus hold onto the pins better,

you will also need to splay the pins slightly to fight. (picture to come)

Ever overdesign and complicate something only to realize later there is a much simpler method? well, I did. I've included a simplified version that doesn't require that you completely disassemble the fan…, it's printer friendly, only need supports on the main body.

I've also added an experimental body to attempt to create a cortex when cooling and direct more air towards the right side port.

Fixed some fitment issues for where the fan screws into the toolhead

Finally got around to testing it and it works!

This is a custom part cooling fan shroud and housing for use with a Beacon Rev H for bed leveling. (it is also slightly modified so that an e3d high temp nozzle will fit, by moving one of the outputs over a couple of mm's)

What it does is it makes the part cooling fan thinner by shaving the top off of the the stock fan housing, and thinning the bottom part of the fan, with some other adjustments to the thickness so that it provides room for the Beacon Rev H to mount under the cooling fan. without bumping into the nozzle cleaning platform.

It requires a few things, 

1. there are a few options, 
   • easy option: the pins need to be bent back as close to the PCB as possible. I started the bends with the plastic housing still on, then completed the bends with my fingers once removed.
   • then you need to splay the pins so that they can fit a molex 1x4 but instead of using standard moles female pins you need to use micro moles pins which are usually used for 2x(x) plugs. you sound down the front of the moles plastic housing and push the molex female pins through so they can seat all the way into the beacon pins

(My fingers were coated in silicone it doesn’t harm the board Just makes it a bit ugly and allows me to still feel everything without gloves)

• hard option, solder the pins away, and resolder the wires directly to a connector for the usb cord
