DIY Infinity Dodecahedron 4K 

1. You need a 3d printer

@@gabrielgraf2521 no need

the trick is 2 pair of mirrors, one BEHIND the light source and one in between your eyes and ABOVE the light source, this last mirror MUST BE 50% transparency, what it means its light passes 50% and bounces 50%, the first mirror is 100% reflection so light gets trapped and multi mirrors the images, making that astonishing effect.

@@chilesuicmez or just two way mirrors with the reflective side facing inward

also do you know what version of the frame you used? I tried to reinforce the corners in later versions

@@quadsquad3087 I used frame version16.skp, mad probs for creating this one!, i tried making my own with Fusion 360 but did not succeed in making the right angles for it. Yours was very nice, but i could not really fit the plexiglass inside it. I dont know why, i printed the parts with an Ender 3 (PLA) and again with an Ultimaker 5 (tough PLA) but it seemed like the plexiglass was a little bit to large (long) for the frame parts.... I checked the sides and they were exactly 150mm.... So your frame parts were coming together, but not like they should i think. I inserted the plexiglass after making the full dodecahedron with your frame parts, this is why i needed the support pieces, because the structure was a little bit weak without them. The support pieces strengthen the structure and keep the plexiglass nice inside.

@@chagay yeah, I spend some time in sketch up modeling it, having no right angles sucks. In the end i think it was 152mm edge, so maybe I scale it down and then plexi wouldn't fit. I'm waiting for led strip, and will build second one, can you share your corner pieces?

@@quadsquad3087 Corner pieces are linked in the description; www.dropbox.com/s/m0rywqdly0ykcm8/Edge%20Support.stl?dl=1 If you want the Fusion 360 files; www.dropbox.com/s/t0w4vo1rvot13u2/Edge%20Support%20v2.f3d?dl=1

@@quadsquad3087 Maybe you should make some kind of diffuser for the light, a transparant 3d printed piece that makes the leds nice and diffuse, i think this will make it even more awesome to look at!

Led strips overlap the frame parts a little bit indeed, you could improve the frame parts by making them the same size as the led strips... but you do not really see it in the end result.

My mirror foil did not have sticky material, i applied it with soap underneath, and carefully removed (95%) of the bubbles with a credit card. I firstly glued the frame (like you can see in the pictures in the video) and then forced the plexiglass in (they snapped in to place) Soldering inside can be tricky, thats why i put the plexiglass in last, then you can insert your head through 1 pentagon and solder a little bit better......

Hi, like said in the description, i never power it to 100% brightness. Than you would need much beefier cable, and i wanted to make the wiring not visible. I run until 50% brightness max, then i can already feel the wires warm up. 50% brightness is more than enough light!

@@chagay Can you let me know what the specs/type of power adapter you used?

​@@beepbapboop126 I used one of these; nl.aliexpress.com/item/32670505021.html

A smaller version indeed sounds cool! What you need to realise is that these WS2812 leds are controlled by an controller (can be arduino/SP107E etc...) They have a brightness that is settable between 0-255, so you can run them at very low brightness and keep the current very low. When i ran the leds at full brightness, all the leds try to consume their max power, but because we feed the leds with 5V only, the voltage will drop the longer the led strip is. That is why the leds at the far end of the 5 segments, only receive about 3-4V, and therefore cannot light up to their full brightness, so they do not use the max current whith what you are calculating. Anyway, there is absolutely no need to run them at full brightness, they are super bright at half their max brightness level already, and because the mirror foil "darkens" the inside of the dodecahedron, even in daylight the leds are super visible.

Hi Carlos, i used 2mm thick plexiglass!

Sides were 150mm indeed ;)

Hi, i used Fusion 360 to just draw a 5 sided-polygon with sides of 150mm. Then i gave that to a friend of mine who has a cnc cutting company, and he cut the plexiglass for me. He used a high quality HAAS mill to cut the plexiglass.

@@chagay Hello , could you send me this file you sent to your friend? I will be immensely grateful for your help! Thank you! Carlos Perrota

I ordered the linked mirror film 2x and both rolls do have mirror tint (well, no perfect mirror tint offcourse ;)) I do not have an Amazon link....

@@chagay Thanks for the response. I finally found a good one that has stickiness, clear mirror, and does not leave bubbles. HIDBEA

@@PaperDragons Could you pls link yours? It sounds good. Searching for one which leaves also no distortion while mirroring.

I ask 650 euro for it, excluding shipping. If you're interested send me an email on chagay@outlook.com. I currently have one ready to ship, this one I added diffusers to diffuse the light, which looks much nicer. Will upload a build/demo video of this one soon.

Sure! Contact me: chagay@outlook.com
