1/27/25: V1.2 updated, fixed some holes in the screw holes, better fitting bearing sleeves,and the shape of the internal portion, reduced part numbers so that the screw stays are all one piece.

UNTESTED! my printer has been dismantled for some upgrades so I have been modeling this just for fun in my spare time. I plan on using this myself. and will update with any changes as I test it. Testers are welcome to provide comments to me for changes or remix their own with the supplied STEP file.

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 removing the stock fan housing, and thinning the top part of the cooling 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. the jst-ph plastic male housing be removed from the beacon sensor, it is a friction grip and should slide off with a pair of pliers,
  2. there are a few options, 
    1. 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.
    2. hard option, solder the pins away, and resolder new 90 degree pins, laying down facing towards the back, you can do this on top or bottom. of the PCB
  3.  either 
    1. custom print a jst-ph female, which I've supplied and have NOT tested and pin your own, 
    2. or file/sand down all edges of the Jst-ph plug so that it stands 3mmx10mmx6.5mm, I did this option, but I did not do it to the OEM plug, i made an extension and did it to the extension plug. 

Here is a link to a fan that can be used to be disassembled. since you're using the new fan housing and shroud, you won't need the fan housing to be a widemouth.

it is the one called "Replacement” that has removable bearings and removable housing. it is also MUCH quieter than the OEM one. maybe order both to be safe.

Here are some good instructions on how to disassemble a fan so that you can use this housing. save the bearings and the lock ring if you don't have spares and reuse them.
