The official LCD support for the latest Josef Prusa i3 kit!

This is a RepRapDiscount Smart LCD Controller support originally designed for a Prusa i3 kit from Voxel Factory (an EiNSTeiN variant of the 3D printer).

The threaded rods are 10mm, don't hesitate to ask for a custom bracket.

The good news (or bad) is that there is no other material than plastic.

Show your make and remix please...


See Prusa i3 Plus kit assembly - 6. LCD for a complete visual assembly guide.

You'll need to extend the ribbon cables before installing the LCD at the front of the printer. Right now, the cables I'm using are 60cm long each, the panel is still functionnal.

Slide the brackets on each side of the printed circuit board (PCB) on the rear side, open holes faceup. Insert the PCB into the cover while aligning the brackets with the slots. The inside of the slots and the surfaces of the brackets must to be clean.

The brackets then snaps on the threaded rods at the front of the Y carriage.

I love the design. I would love it even more if you made the supports in an 8mm version, since that's what my printer uses. :)

Only printed one of the backetrs for 8mm rods (that clefranc whipped up in a matter of hours), but it fits like a gloove. I am sure the otherone will be equally great.

I really like this design, nice job!
Are you able to make mounts for it to fit the sunhokey prusa i3 2015 model please? its the 6mm acrylic version - can email you photos and measurements if needed :)

Im just about to make a similar machine . Show me some pics with dims and ill do some mounts for you

Thank you Phil. Do you have an email i can send pics and dims to plz?

check your messages inbox

nice print. thanks for the effort.

Thanks. Prusa's own i3 cover in sdlprt comes handy!

Just printed this, had the same problem with the 10k pot on the back of the LCD board. I solved it by cutting out a chunk of the support so that it could slide over nicely. Maybe reprapdiscount is putting this larger pot on all their boards? That or Artaex and I both bought the same clone ;-)

Very happy with this - looks great and cleans up the machine really nicely. I'm also using the 8mm rods but this isn't an issue - am not planning on mounting this in front but just letting it stand to one side of the printer.

Awsome model! Im just running into a problem with it being front heavy and trying to fall over. Ill post some modified legs when I get to it.

Hi clefranc, thank you for your good design.
I'm using M8 rods too. Is it possible for you to upload an M8 variation?

Is it done with OpenScad? If so, could you upload the source? I'm able to change it to M8 variations.



I just broke off the potentiometer on the back of my PCB. Might want to increase the space between the PCB clamps and the support.

You mean R1? I really don't know how the bracket can damage it!

The contrast thing broke off.

Unless we have a different model, my contrast pot is only 2mm thick. Can you upload a photo? OK, just saw a picture on Google Image, you have the big blue square potentiometer, now I understand. Will try to update the bracket shape, from Google images...

It sticks out like 7mm

Is it just me that gets the Prusa letters mirrored ?

Nop, i also have it mirrored. I can not make it work.

I am using it on M8 thread rods with no any problems

the rods are M8 or M10? will this fit on a standard M8 i3?

I've updated the description.

Is made with OpenScad? can you publish the sources? I wanna make some cosmetics changes and could be easier with sources. Many thanx, good job.

I've sent a private message about this project. Reeally Nice ans usefull!!! Thanks!
