HELP creating geometric shape for 3D printer

[Griffinmcg]

Let's go with 76 mm wide for each of those triangle bases. I'm not looking for it to be super exact to my plaster copy. Just this symmetrical on all sides geometric shape. :-)

how many f****ing triangles are there on each square ?
6 or 8 ?

I can see there's a trinagle with long base a,long the cube - but how many are there of upside down ones ?
It has to be another 4 right ?

Each time I look at that bloody model I see different numbers.

my brain hurts lol

I'm about 90% there, just having trouble matching the damn triangles up

At this point, I'd be opening Tinkercad and dragging pyramids onto the work plane. Griffinmcg, consider to do just that, to bring up a model that removes the confusion.

[Griffinmcg]

Haha, there are 8 triangles on the top half of the shape and 8 triangles on the bottom half of the shape = 16 total. Then 1 flat square on top and 1 flat square on the bottom. I thought it was pretty simple when carving it from cardstock paper but now the more I look at it, the more my brain begins to hurt - haha!

how's this ?

going to print one - just because it's such a weird shape lol

[Griffinmcg]

That looks like it's a match!!

[curious aardvark]

The weird bit that makes it strange to look at is that the trinagles on the long sidees lean outwards, while the upside down ones on the corners lean inwards.
And your brain doesn't believe they can meet up :-)

Tricky bugger - but I'm stubborn :-)

I made a video - first time I've ever made screen capture video. Windows game bar makes it dead easy :-)
it's fun :-)
And there will be more !

[Griffinmcg]

I should have taken better photos from all angles before I left the house today, but it looks like you nailed it!

[Griffinmcg]

Great video! It looks perfect. Now how does one get their hands on that print file to avoid hours worth of mixing and pouring plaster? Haha ;-)

[curious aardvark]

so what's it worth to ya ?
