I just printed this, and it works like a charm... but, do I need to "ground" the psu to the printer or some other thing, when I take it of the printer frame?...

Hi, I like the simplicity of this design however I was curious as to the effect on the cooling of the power supply considering that the vents on the backside of the PSU are flush up against the underside of the table top and covered.

Have you noticed if it is running hotter now?

Thanks

Is necesary to buy a kit of wire extensions?

No, you don't need a wire extension for the power supply.

OK, thanks!

Hi DAVYcr, Is not necesary bring all the electronics out of the enclousure? or the heat only affects the PSU?

If your enclosure is enclosed on all four sides, it's probably best to move all electronics outside of the enclosure. Mine is only enclosed on three sides so it's not a concern for me.

Yes, will be enclosure on all 4 sides, so I will need to figured out how move all the electronics with original cables (no chance to get an extension kit soon here in argentina...)

Looks like you used a grommet or something for the hole where the wire goes through. Where is the STL for that?

It's an STL under this thing: https://www.thingiverse.com/thing:3358985

The STL is named "cable_guide.stl"

I'll add it to this thing as well, thanks!

How big did you make the hole to run the cables through?

Sorry for the late response! Looks like I made it ~7/8" (~22.25 mm) in diameter.

Hello, do you know of a similar mount for the main/motherboard box for the ender 3? Everyone seems to be designing boxes from scratch and I just want a simple bracket to use the existing one.

I'm not sure what you mean, do you have a picture of what you're talking about? If you provide dimensions, I could probably whip something up for ya

I'm talking about the only circuit board aside from the control panel that typically mounts under the left front side of the printer, the box where your USB port and micro SD card are.

Isn´t 2 just enought to support the Psu? why 3?

"You should be fine with only one mount and one end bracket. I used an additional mount to better distribute the load."

Which psu cover do you use with the supports?

None of these require supports, just print the parts oriented on their sides.

The project is listed as supports "no". Am I wrong, I don't see how it can print those hang over portions without supports.

Rotate the parts so they are laying on their sides in your slicing software and you won't need supports.

Oh no (face-palm) you're right.

Excellent! Going to print this for my Ender 3 soon as my brackets for my enclosure are complete. Now I need to find one to fit my Ender 5.

Thanks! If you end up liking the design for your Ender 3, feel free to provide dimensions for the Ender 5 PSU and I can make/upload a compatible version :)

My Ender 3 non-pro PSU measures (HxW) 49mm x 114mm.

Awesome, thank you! Will add a non-pro variant this week and let you know when it's uploaded.

Also, I would encourage you to update your profile so you can be left a tip...

Thanks for the idea, totally forgot about that lol just added! Will reply to your other comment once I get the base PSU mount uploaded. Definitely a fun project, the printing just takes some time. Cheers!

Sweet, when it's up I'll print it out and let you know about the fit. Going to build your enclosure this weekend (just got home with the hardware and plexiglass sheets), should be fun :)

Just added STL files for the base model PSU per the dimensions you gave me, let me know how it fits!

Thanks! Will do! Might take a few days, have a lot of stuff to print for my enclosure project :)

Hey dude, Might be an idea to include PRO in the title as the Ender 3 and Ender 3 pro have different PSU's, The Meanwell on the pro is much smaller overall

Updated. Thanks for letting me know!
