I tried printing this and the bottom half had a catastrophic failure where the print nozzle bumped into the tiny sections in the hex pattern you put on the sides.

Was I supposed to put supports there?

Nope. Shouldn't need any supports. Sounds like you might have had a layer shift? Try to print it again but slower. Do .12 layer height and 40mm/s. :)

Could you adapt the Design for the LM2596S? I buyed 5 of them by accident just to found out that they are a bit smaller than the lm2596. They are just a bit smaller in length while the width and height are still the same. But since i don't won't to ruin the hexagon shape and you are actually the only one here that is not just producing total bullshit, i hoped that you could edit it for me and add it to the package.

Thanks for the compliment. Let me see what I can do. I might need you to take some measurements for me. I will let you know.

How easy is it to remove the enclosure if I want to mount it somewhere else on the frame?

You can just pull on it slowly and it will snap out. If you want it to last a bit longer, sliding it in/out works well. I use this enclosure in several places as well. :)

The first layer of the lid doesn't print well for some reason. It first looks like its under extruding, but I think that's not the case. Can it be the gaps in the Cura slicer?

Think I found it, the first layer has 4 "stripes" that messed up the print...
Does someone know how to fix this?

Hmm. Thats really odd. Try lowering the whole thing below the print plate by a tiny amount and see if that fixes layer 1.

Anyone has an idea what Cura is trying here (see attached image)? Usually I prefer zig zag for top and bottom. But with this model Cura skips some parts every second layer. I switched to concentric which seems to work fine - currently printing...

Great design. How is your raspberry pi mounted to the rear of the LCD screen?

want to give these a try - they look cool. do you use supports for the tabs? Looking at the overhang there is probably no way to print this without, am i right?

Yes, supports for the tabs are a must. However, the ones in the lid print just fine without supports. :)

Hello,
I have tried to print one for me. But the base didn't print well. There are some problems in the stl-file. There are gabs between the inner parts and the Bottom.
On the Picture you see the gab between layer 12/13/14 if you print it with 0.15mm
I have load the stl into DesignSpark and you can see the gab, too.
Regards,
Heinz

Fixed! New files added as well. Thank you for catching this and giving me the chance to improve it.

Thanks,
after my holiday i will make one with the new files.

Fixed. Thank you for your post and giving me the chance to fix it. :)

Hmm. That is definitely an issue! Let me take a look in my files and see if I can make a fix. Thank you for bringing this to my attention.

Hey thanks for this! Printing one tonight to go with the Adjustable 2020 USB LED Mount you also made :) , Could you please provide a wiring diagram to take the power from the printer power supply to this converter. Also do you please have the 'thingy' file for those smart little 2020 wire clips your using in your pics :) . Thank you very much

There are labeled + and - "out" terminals right on the board. All you do is run two wires to two empty + and - terminals right at the bottom of your power supply, under the cover. ;)

Here are the clips: (I love em) https://www.thingiverse.com/thing:2673266

Fantastic! Thank you very very much. Great designs too.

Thanks mate, im gonna use this one on my AM8

Awesome. Post a make when you do. ;)

Just curious, what is this used for. Great looking design.

There are many uses but I used it to run power from my power supply to this buck converter, reduced the 24v to 5.1v, and then micro usb cable out to power my raspberri pi. Now, I just plug in one cord to power on the whole system. ;)
