Thanks for this design!
I just printed the Factory screws with buzzer
and it didn't even take me two minutes to fit it, no adjustments at all

This comment is currently flagged for moderation.

Ender 3 models now has 5,6mm head screws, so the factory screws version aint gonna work. Before printing that version its important to mesure the size of the screws.

Just FYI, I just got my Ender 3 last week and printed the factory screws version with no editing of the model. Fit just fine.

nice too know, but the holes in my part for the factory screws have a innerdiameter from 6,5mm

Sorry, the screws are 5.65 actually, it leaves .85mm space.. not too much margin of error.. but maybe try with brute force or buy the screws and print the first model..=)

Adjust your printer and your slicer correctly and 6.5mm holes are also printed with 6.5mm diameter.

As I said, the holes are suitable for the screws. If the holes are too small in your print, then my model is not the problem (otherwise I would have liked to change it immediately)

Lets do this, im gonna print it and let you know. At this time i dont have printing size problems, so this print must have those 6.5mm when done. I let you know the results.

Rocco, I guess i had the problem with a remix. (https://www.thingiverse.com/thing:2987100), my mistake sorry. But ive printed again yours and fits, quite tight but it fits ok. The printer messure its ok btw. Maybe a 1 mm or 0.5mm wider diameter will help with not so calibrated printers.
Thanks a lot and great work.

ENDER 3 FACTORY SCREWS display rear cover

All right, just wanted to know where the problem was.

For criticism, I am always open;)

Hi Guys, I just had a weird problem, the printing was okay for 2 hours and in the final 30 min the extruder went backwards and ejected the filment, any idea of why?

Printed the version with factory screws and hole for the buzzer. Really nice design. Thank you!

Both the factory screws versions have the buzzer hole.

For real? I will check and fix this tonight. Thanks for the information.

Have you had time to fix it yet?

sorry forgot it.
Have just changed and re-uploaded.

Awesome, thank you!

hello can you share the step file? or the lcd model? thanks

nice design fits reallt well, dont know where you guys are getting bell from though a bell rings a buzzer or sounder beeps :-)

What is the optimal screw size to attach the cover?

If you like to use the factory srews, use this one:


or with silent buzzer

Hi guys, I have just started printing and when I tried to print this it created a mess after the angle of the wall changed on the bottom part (around 30 layers up). I didn't add any supports, as I thought the angle was doable (20 degrees). Any help would be much appreciated.

Settings used.

Nozzle - 200 degrees
Bed - 60 degrees
layer height - 0.2
Wall thickness 0.8
No supports
Print speed - 60 mm/s (could it be printing too fast)
Stuck to the bed fine.

Am I supposed to remove the bell? Is that what the one without the bell is for?

You do not have to remove the bell.
I have uploaded versions for with and without bell.

Removing the bell is easy. Heat the two solder contacts on the top and pull the bell down. It can then be mounted again at any time.

I was annoyed by the beeping.

Also interested on how tout remove the Bell

Thank you so much. I was worried about pricking my fingers/getting zapped or damaging my lcd board. Gonna print one out ASAP,

Yes I did not like the open board.
Nice that my cover so many like!

A good addition to this would be a few differently positioned slots for a SD extension holder. I'm not sure if an extension cable holder has been made yet for the Ender 3, but it definitely needs one of those microSD to SD extension cables. It's hard to get good visibility of the microSD slot and there is sizeable gap above the slot. I've lost my card twice into the gap before I finally got the cable. With the cable, life is much easier.

Ender 3 - Micro SD to SD Card Holder

I'd a version that just covers the bell, muffling it a bit more. did you cut your bell off?

I shoved some silly putty in the hole for the bell, it does quiet down a bit, but I would leave the bell covered to muffle it down some more. Before I did that my wife would hear it at night in the bedroom upstairs.

Comments deleted.

To designer: I suggest editing the title to include "Ender 3 LCD Cover" as well as I would think that's what people would be searching for not only "display" I tried finding this for a bit ended up having to have a youtuber link me to it :)

Do I need longer screws?

Yes, 2x M3x8 and 2x M3x16
