New GreenAntz 2.2 case design for Zebidee to mull over ;D Well it is green!

Zebidee:
Wow, it looks very nice indeed Ond. Love your work, thank you so much!

Oh, I'm definitely mulling! Mull mull mull mull... "The Mouli Mullamatic, it work liiiiiiiiike magic", old advertising jingle some mates came up with for a music school assignment, they'd sing it a capella all the time, ear worm still stuck in my head after 25+ years....

I think it needs "GreenAntz" text there - if stylised is too hard, then simple text would do.

I've been juggling ideas to extend the LEDs to those holes. In theory the legs could extend from the PCB, so that the LEDs actually reach those holes themselves.

Alternatively, some 3mm fibre optic. Glue one end into the hole (carefully, so it lies flat) using either clear epoxy or even just superglue (gotta be careful with that stuff). A little pre-shrunk heat-shrink tubing, slightly recessed, could help it sit properly and increase surface area for glue to hold. The other end can be have more heat shrink tubing, longer, that also extends over the head of the LED, pre-shrunk to fit. Slip it on and screw the shell halves together. Maybe another big blob of glue or silicon inside the shell to hold it there.

Feels a bit fussy and fragile though, at least where it would be glued to the shell. Obviously I will have to experiment.

If we do fibre-optic tubing then maybe the LEDs can be the GreenAntz' eyes? That would be pretty wild.

Oh, and shell colour doesn't have to be green despite the name lol.

I'm already getting some prototype shells printed, basic version of this design (no logo, wings, LED holes). Will share some pics here in a few days.

Ond:
You're welcome :) Note, the case has been designed from scratch although I did use your supplied model as a reference.

More pics including added text. You can see how the moldings work including the tubes to LEDs.

...and in my preferred color

I don't recommend any tubing/optical fiber etc. The LEDS will be plainly visible when viewed from above which means less work for you. In testing I've found that white optic tubing does not work very well anyway. I'd keep the text under the logo plain. Stylized font will look too much IMO.

buttersoft:
nice case design, Ond!

Zeb, i like to use round perspex rod for light pipes on my designs. Hole tolerances on the print can sometimes be tricky, but once you dial it in you just cut a short length of rod, file it flat on the top end, and press-fit into the hole.

PL1:
Looks great, Ond. ;D

Instead of the current straight-sided LED cylinders, you may want to consider using tapered cylinders.

One way is to slightly increase the outside hole diameter so there is a (5-15 degree?) larger viewing angle -- no light pipes needed.

Otherwise, you can add a thin, 6-8 mm tall vertical slit across the bottom of the LED cylinder walls (red lines) and use a very slight taper on the bottom 1/4 or so of the cylinder.
- The slit will allow the bottom of the cylinder walls to flex a bit for better friction while making the tolerances less critical.
- This makes it easier to insert the light pipe into the top then press it down for a flush friction fit.
- For more flexibility, you could add a second slit so the bottom is divided in quarters instead of halves.
