Micro-Swiss Linear Rail Plate Cooling Duct w/ BLTouch (or not)

While i have tried, and do use the other 2 available ducts for the Micro-Swiss Direct Drive units, I found that they are not the easiest to use with respect to when you need to do maintenance and are taking them off and putting back on.

I believe the housing for the Hotend fan can be fitted with a nocturna unit, but since i do not use them, it was just guesswork on fitment. The Fan Mounts are punched for using the 2.5mm brass inserts or a 3mm screw.

The model was put though MeshMixer for the tree supports and I include the bare STL and the Supported STL.

I am also including my GCode sliced in Simply3D for PETG. adjust your temps accordingly.

For the Extruder knob i am re-using the design of knob with my last Fang Duct from Briss-Moto. I did make a mount for it to go on the top of the cooling center, which is included, also made to use brass inserts for the stub-mount. I cannot include the Briss knob because it is not mine but this one is similar...I will contact Dominic and see if he will allow me to put his it in my file list in the near future also.

Knob Support V2 is meant to also get brass inserts top and bottom of the base and be affixed to the top of the assembly then the actual knob part can screw into that which makes for an easy removal.

The other issue i had with the other duct systems was support for the original positioning of the BLTouch mount from Creality. This cooling center model supports using the one that comes in the box for the Ender 3 from Creality and it is fitted under the two mounting points and held in place with the same screws.

I mainly design/print functional items, and pretty much everything in PETG using overture or hatchbox filaments.

I use a Micro-Swiss Direct Drive system on a Linear Rail, and have also used it on the standard POM Wheel system along with an M2 Nozzle on the MS Hot-End...Excellent in my opinion.

Micro-Swiss likes the design and suggested that i add some more venting on the flat side, V2.2 is now vented on the side.

*note: this will work on a standard Ender3 Pro system also

242 on the Hot-End and 70 on the bed. I use a thin layer of glue stick to better hold the support system used in this print. Dont let anyone tell you that using a glue stick is cheating, it is the difference between losing material and time... or a successful print (sometimes).

Also ver 2.2 has some overkill with the bases for the supports. Using a skirt/brim of 4 to 5 this will connect all the support bases to the model further insuring this almost 7 hour print does not loose a support causing a failed print.

These supports remove very easily for PETG. It is not recommended using cooling enclosures with PLA.

I test print every revision i made so i know the latest revision is good. I recommend using the Supported version 2.2

Note i also have found that any of the transparent PETG from overture is stronger/more rugged for these types of things but go up to 243 on the temp with that material.
