@Pepijn Here's how I solved that problem.

I'll use this as a thread to document the building of this toy.
Idea: https://mastodon.online/@Pepijn/117257481074439294
Electronics: https://mastodon.online/@Pepijn/117293604254967877
Current phase is creating (in #FreeCAD) the physical box, some internal support structures for the electronics, and the faceplate. As it has to be herd-of-small-children-proof and maintainable (replace batteries, change sounds for further use) it's a fun learning project to figure out the design requirements for that.

Update: #freecad 3D model is basically done. After figuring out threaded inserts I'll print it.
I added a little slot for the speaker. The backplate is locked in place by the faceplate.

Someone asked if this is all worth it for a halloween costume.Well. I'm fairly certain toddler would also be really happy with a cardboard box and no sound.
Toddler also enjoys participating in this though. And I'm learning new #hobby skills.
So yes. It is, as we're having fun.

I forgot who I chatted with about this, but just to confirm: When I complete the toy I'll create a short page on my website with part list, .stl files (in various versions) and building instructions.

edit. Correction: replace iPhone with Large Hadron Collider.

@Pepijn may I suggest you share .step files or even .3mf files instead?
And the freeCAD files as an extraMakes it so much easier to adept your design, if needed

@LegoPink Good idea.
Are .step and .3mf files exported from FreeCAD easy to work with? I've never tried that.
My original FreeCAD files are extremely messy as I used a base file that includes a lot of comments (to myself) so without a rebuild I don't feel comfy with that

@Pepijn
Good question, actually...
If imported .stl files in FreeCAD and was very annoyed with it. Never tried importing someone else's .step ffilesI always export to .step or .3mf, (never .stl)
And import with OrcaSlicer for 3D printing, works for meTotally agree on not being comfortable to share some of my FreeCAD mess...
Still learning modeling -

You might consider self tapering screws for plastic instead. -

You might consider self tapering screws for plastic instead.@NUeB That usually works but for this I'm trying something a bit more durable and toddler-proof.

Hurrah! Threaded inserts are nice!
Photo is a test I did with different hole sized and wall thickness.

Update: 3D model is done (screenshot is of an iteration just before the final one). Tonight I'll put together a little circuit board to slip into recesses printed inside the box.
I take great joy in how massively overengineered it all is. Tricks learned will be great for future projects.
Next is printing, sanding & painting, and assembly.
Then we'll have to figure out some daycare appropriate sounds (so: barely audible, gentle, not-fucking-annoying)

Today the 3D designed parts were printed and passed the test fit.
I also collected all other components (yes that's lego, and yes I'll glue it) and knolled them together for a fun photo

Quick update: parts got two base layers and the first yellow coating. This is the look I was hoping for and I think I'll be happy with just one more thin layer.

Update: had a busy week with a last minute work trip abroad. Managed to do some painting (last yellow layer, black lettering, transparant coating) in-between though. Due to time-limitations I did simplify the design. Very happy how the SCIENCE 3000! pops out. Toddler will certainly appreciate that in the four seconds they'll use it.
I hope to connect the electronics tomorrow evening.

The hobbit and I made a start with the recording of "science" sounds.
It's gonne be a tough one..

Installed the LEDs, resistors and decorative lego. Background noise: The Hobbit is doing their part in the project by hitting both their drum and the 3D printer with a drumstick.

@Pepijn Ho! Op de printer was niet de bedoeling hoor ik
