Elecrow 7" Touchscreen Rackmount Case

I designed this for my touchscreen since it needed a case, and I wanted to be able to mount it inside my rackmount print enclosure. 

After connecting it to my OctoPi system and configuring/setting up OctoDash, it worked right away--it's proven very convenient for displaying status info/entering quick commands/checking camera feeds/etc. at the enclosure without having to jump to a desktop or mobile app.

It was designed to align with all of the items on the back of the screen; speakers, ports, and so forth--you're not going to be able to fit a RasPi inside the case (mounted directly to the screen), though the mount points are still accessible, so you can certainly still use them if you have some longer mounting screws.

The spacer between the rack rail and the body is to allow enough room for cables of various sizes to be connected easily--I used an HDMI cable with a relatively large plug, and it still worked well.

PRINTING

Material choice is up to you--PLA is likely fine unless your enclosure is heated. PETG is probably a better bet; any other tougher material should be fine. No need for supports, special preparation, or post-processing.

I printed the base out of TPU which I… don't recommend since it takes a ridiculously long time to print and ends up being humorously wobbly. It did work, however, so I just printed the lid in PETG and then stabilized the base to the top of the enclosure with a zip tie. It all worked out nicely, but… again, I don't recommend doing this; I just did so because I've got way more TPU on hand than I know what to do with.

USAGE

I designed this to be mounted on the upper-right of the enclosure front rails, but it should work in any location; just be sure to flip the display orientation in software if you mount on the left.

The holes are sized to self-tap a standard M6 rack bolt; depending on your printer's dimensional tolerances, you may want to heat the bolt a little bit and screw it in slowly to facilitate the first installation. 

Attaching the top to the base is accomplished with four M3x25mm nuts/bolts. It's 26.5mm from top to bottom, so any length greater than that should work. Pulling the captive nuts into place in the slots on the back before attaching the lid will let you install it easily with 25mm screws.

I borrowed the idea of adding stabilizing bumps on the rackmount section from Robagon3D's outstanding enclosure accessories. If you haven't checked those out, you absolutely should; there's a lot of cool stuff in there. The bumps are very useful when first installing the screws--helps keep it aligned; if you have rack rails with round screw holes instead of the square openings, just add a negative volume in the slicer to smooth off that area.

COMPATIBILITY

“ELECROW 7 Inch Monitor Compatible with Raspberry Pi 5 Screen 1024x600 IPS”

It was designed based off of (a lot of) measurements of the latest revision being sold as of September 2023--if they change the form factor significantly sometime later, I can't guarantee alignment.

I designed this for my 12U Navepoint Performance rackmount enclosure, but any standard rackmount rails should be fine.
