These are the files for the 3d printable case.

Nice! I have a question, though: What is the difference between Cover2.stl and TerminalBox.stl? They look the same, but maybe I'm missing something? A comment as to what the difference is would be nice.

Whoops! Wrong names...

Cover 1 is the Terminal Box Terminal Box is Cover 1.

Cover 2 is named correctly.

I have NO idea how the names got transposed.

Just pushed the right naming.

hanshuebner commented 4 years ago

The case looks good and fits the PCB well. I wonder, however, how you intend the cover to be affixed to the body. There seem to be no snap-fit hooks or anything. Are you using Fusion360 for modeling? There is a nice tutorial on how to do snap-fit lids here: https://www.youtube.com/watch?v=VVmOtM60VWw

Maybe I'm missing something?

The "catches" on the sides of the top do actually catch -- friction (and it fits tight) I wasn't trying to "lock" the top on... It could be an enhancement (sinceI wasn't designing it to be upside down :- )

I was playing with trying to keep the inside walls smooth, prevent them from getting too thick, etc. and didn't want to add a lip because it would allow the PCB in general "slide around". I'd have to thicken the walls and add notches, etc. for them. All could be done. All a time/effort/speed set of tradeoffs.

I'm not using Fusion360, I've got other tools...

I could do additional work... will have to think on it. How many of these boards are you selling?

Have you printed out one yet?

Hi Earl,

I've printed the case on my Prusa i3 MK3 using generic PLA filament, see the photo in my previous comment. The lid does not stick to the body at all.

I have just built the terminal for myself. As usual, I have a few more PCBs and might sell them, but that'd be only for my amusement. Maybe I'll just pass on the PCB and the programmed controllers.

Cheers, Hans

Hmmm, I printed on my Stanley Model 1, and I can turn it upside down and the top doesn't come off. It has PLA in it right now as well. (funny we both printed in blue :-) )

I have a previous one here and I can shake it the top doesn't come off until I get pretty violent with the shaking.

I just did some looking at your picture (it didn't come thru in the e-mail thread so I was rather confused... I had to go to github directly to see it... ) and maybe your printer just generated smoother surfaces. That could be it...

I will print another for a friend (who bought one of your boards here as well.... ) and see if the size change made any difference. When I have some time, I'll see about tweaking the catches to make it a more "mechanical" vs friction fit. I could go with rounder ends on the ends of the existing legs on the top and then put dimples in the insides.... that would give a better grab but not make it impossible to get off.

But does it work ok as a case (aside from the top issue) for you?

Hi Earl,

no worries, I'll just tape the two parts together. It won't look as nice, but it'll be much better than the bare PCB. I have some plans to redesign the PCB to include a RS232 level converter on the board, but it is not a high priority project at this time, so for now, your case will do just fine :)

Note that I'm not the author of the terminal code or the original code, but just a user.

You could always put super glue on the legs... if you don't want to open it easily :-)
