Ender 3 Electronics Box w/140mm fan V2

A "V2" as such, of this design https://www.thingiverse.com/thing:4379127, made by kylelmoy.

Changes are as follows: For the motherboard and buck converter tray/plate, I reinforced and changed the mount surfaces for the base of the enclosure. Now you no longer need to screw / unscrew the mount to get to the board. This design uses two slots that you slide the motherboard plate down onto. I might try making a design to the chassis to make it faster to take off later.

I also added spacers/standoffs that should help avoid an issue I was having, where I needed to use longer screws to mount the board, due to the soldering points on the back of my SKR Mini E3 V2. (It probably works fine with the original design, as it's plastic, so the soldering points shouldn't short or bend.) But with this design for the motherboard plate, it should work overall a bit better.

Secondly, I gave the control panel standoffs like the motherboard and buck converter. I was running into an issue where the control knob component was colliding with the chassis, meaning I couldn't get a flush mount. The 3 other corners were mounted much closer to the chassis, making the finish look a bit skewed. (Also potentially adding more pressure on the control knob)

Adding standoffs on the chassis however has a drawback, as with how you'd most likely print the part, it means more overhangs. You might get away without supports, as they standoffs don't stick out too much. With the redesigned motherboard plate, you'd print it with the standoffs facing up.

Thirdly, I added a version of the base without the mesh grille, as I am planning on using a removable dust filter between the fan and bottom. The original is included however, with the neat hex pattern. They'll work interchangeably.

I've only updated one of the two "trays" included in the original design, as I don't need to mount anything other than the motherboard and the buck converters right now. Files with the "New_" prefix on them are the ones I redesigned/changed. "Original_" prefix are the ones from the original post, so you don't have to download both.
