Prusa MINI - X-carriage with better cooling

This is a modified X-Carriage for the Prusa MINI with part cooing ducts for the Revo Micro and the Stock Hotend.

Remixed from solderjul. Changes listed below.

Updae V26 12.11.2024:

• Slightly increased exit-size of middle duct
• cut of part of the middle duct to increase clearence with the bed-connector
• improved printablility

Update V23 07.04.2024:

• Angeled the side ducts a bit more inwards
• Made a CFD analysis with SimScale
• This should help with better cooling from the front

Update 05.10.2023:

• Pinda mount now has more clearence for hotend wires
• Updated F3Z & STEP files

Update V22 29.09.2023:

• Angled the middle duct more downwards
• shortened the side ducts a little

Update V20 26.07.2023:

• Made middle duct way bigger
• Improved compatibility with stock hotend

Update V19 14.07.2023:

• Re-introduced the middle duct.
• made the middle duct bigger.
• Air-splitting thingies are now fancier and easier to print.
• I remade the entire F360 file for better clarity.
• F360 and STEP files include some of the original components for reference.

Update V14 07.07.2023:

• Removed middle duct.
• Improved geometry where air gets split.
• This will greatly improve clearance when levelling.

Important clearance info:

I filed down the studs in the back of the bed a while ago, so i don't know if it'd work with original studs.

Additionally, i would also highly recommend printing my 90° Bed-cable mount:

It has a lower profile compared to the original connector and a countersunk screw.

You'll also want to install a pair of these little spacer clips on the X-rods, so the duct doesn't crash into the Z-carriage:

Info: The STEP and F3Z files include both, the Revo Micro and the original hotend for reference.

1. The janky cutout for the Pinda probe is gone, but you'll have to print the included SLIM Pinda-holder.
2. I improved the geometry of the little separators on the inside, so it is actually printable, and doesn't just create two huge droops inside the duct
3. I also made the exit-holes quite a bit shorter, so they will actually work with the revo, unlike the original, that is sitting ~0.3mm too low.
4. The geometry on the inside is smoother, because it had a few leftover cutouts that aren't needed with the Revo.
5. Compatible with both Revo, and Stock hotend.
6. Unlike the original, this description is written by a human.
