wow.
wow.
wow.
I am truly astonished
HOW DARE YOU make such a cool item.

This is so cool, did anyone else get this from Zach King?

so there are 2 pieces, do you glue it together?? or is it just an illusion depeding on how you look at it?? easier to see thru camera?

If you expecting it to POP out and look like the picture .. No .. Its all about the View angles , you literal have to look at it in the right position. Don't get me wrong , great design.. Best way to see it , is with your Phone Camera , move your phone til it looks like the picture above ..

Hi! Thank you everyone comments.

In order to properly shape the shape,
Stable shaping without temperature balance and vibration of the filament and head is indispensable,
Therefore, accuracy depends on the 3D printer to be used.

for your information.

вообще полная шляпа, зря печатал

Use the thingy on top. Look at it and cover one eye. Look at one of the edges and make it connect with the lower part. If it fails, try another edge. Do it until you see the triangle.

fun thing to play with

but the printer setting is a bit tricky for the overhangs.

that is the best question yet

Hi! What printer did you use? my printer need supports to do this triangle, and the results are horrible!!! I want to buy another, do you recommerd yours?

Hi! VPassamai,

Thank you for your comments.

Material can be well better of the PLA. Temperature is around 210 ℃.
I hope if there is also a cooling fan as long as hard to cool the temperature of the room is hot .

I like the 3D printer that is suitable also in the overhang .
Better not to use the support can be beautiful .

I like the old model of Replicator2x.

Now , I see that there is a download of the problem . Please wait for a while because the upload again .

I've uploaded again.

My head hurts looking at it!

Awesome model, great job making it we did a time-lapse of it you can watch it here. https://youtu.be/JgSauqC7MQk

that thing messes with my brain! it took me so long to figure out how you made it do that! XD

Loooove this triangle! I've printed so many of the first model. Any reason for the extra overhang in the second? It seems more difficult to hold in order to achieve the same illusion.

I made one but can't figure out which way to view it to make the pen rose triangle

i made a 40% size version just to test first came out good recommend supports for the overhangs some colours work better than others aswell the green i used didn't really work to well but il definatly make another bigger one with a better colour

Does this require supports? Thanks in advance

it doesn't require supports!

No, not on my printer at least.

I'm having a hard time getting this to print smoothly on any of the overhangs. Pretty sure it's messing with the illusion too. Cool though.

Well...
Seeing as it is a famous 'impossible shape'...
I would think so.

Yes. It is an illusion

how did you come up with this? I think I may need to make one

Well done Tomonori! Probably the best optical illusion in all of Thingiverse!

Sorry, but I printed this and I can't for the life of me figure out how to position it. Can you provide any assistance?

Hold it so the pointy thing is pointing at you, then turn the pointy edge to the left and slightly down to align it with the left and bottom sides. Done! (but it only looks right in one specific angle)

to matteeee

Thank you for assistance.
