This is a nice simple case for the SmartLCD display with 6-7mm knob post, built-in chirp speaker, and SD card slot on the left side. The SmartLCD comes with many RAMPS kits, including one from Gadgets3D, which is where I got mine as part of their full RAMPS 1.4 kit.

Two optional 3mm screws can hold the SmartLCD in place inside the case, or just insert the LCD into the top part first before adding the bottom part. The top and bottom are designed to fit together so no additional hardware is required.


I printed this case in natural PLA and it works really well. I had to file down the tall posts in the back a little to get a fit where the bottom didn't bow, so I may bring the verticals inward a little on the next revision.

There are lots of great knobs posted on Thingiverse, or you can use the one that comes with your SmartLCD. I used the one from DeltaPanel by scottmayson.

The smartlcd.scad file is from my own measurements. On mine the speaker was mounted on the back. This is an option in the scad file. You can compare my SmartLCD model to the one by sola_technical.

Any chance you can throw in the STL for the knob?

The knob is from DeltaPanel by scottmayson http://www.thingiverse.com/thing:30330


Thanks - very handy.
I have since discovered that My LCD has a different backing board and doesn't fit this case.
May have to design something myself.

Good luck, and have fun! You can try using my SCAD as a starting point if the form factor is what you want. There's certainly no shortage of enclosure designs on here and Youmagine if you're looking for something to suit your personal style.

I have to learn this SCAD thing. I have so many skills to keep up to date, I have yet to look at it.
but that certainly looks like an option.
In reality all I'd need to do is to throw it into inventor and do a press-pull and extend it a little.

Thanks for the source code. I was able to easily modify the OPENSCAD file for the base so I could add a T-slot M5 screw tabs, making it possible to attach it to the top horizontal misumi extrusion on my mendelmax 1.5. Bonus, the added slant to the original design means that the display ends up almost vertical instead of slanted at the angle of the frame.

Great mod. Please post your "make" with a photo so we can see the concept in action!

Hey, I made this, and it works great, however, I'm wondering how you connected this to your printer? It's hard to operate this box with 1 hand because it's not fixed to anything. For example, when inserting an SD-card.

I can easily draw something myself, however, I'm curious to know how you solved that, or didn't solve at all ;)

I've never affixed it to the printer. But I've given that some thought, and how to make it printable. Rather than try to include it in the design, I'd suggest adding some holes to the bottom and/or back, and then come up with a bracket design for your printer that you can screw it onto.
