Description

To continue on the previously designed tetrahedron lamp, I designed dodecahedron lamp. I also found tetrahedron lamp to be a bit on a smaller side, so this time I wanted something larger. This lamp is 360mm (≈ 14 inches) tall and 320mm (≈ 12.6 inches) wide and deep.

You can use LEDs with this lamp and there is a special frame designed for LED wiring. You can also use E26 \ E27 standard pendant light with this lamp and there is a special insert for that. You also get a stand if you decide to put the lamp on some surface or you can hang the lamp with pendant light.

You will also find two types of films this time. One is simple and plane, but the other has numbering on it to make the D12 dice lamp for your gaming room.

Printing

Depending on the version you choose to print, you can refer to the guide below for the number of pieces that need to be printed.

LED Version

11 Frame Pieces
1 Frame with Hole for LED Strip Wire
12 Insert Pattern Pieces
12 Insert Films (Pattern 1 or Pattern 2)
30 Alignment Keys

Pendant Light Version

12 Frame Pieces
11 Insert Pattern Pieces
1 Insert Pattern - For E26_E27 Pendant Lamp
11 Insert Films (Pattern 1 or Pattern 2)
1 Insert Film - For E26_E27 Pendant Lamp (Pattern 1 or Pattern 2)
30 Alignment Keys

Stand

1 Stand Top
1 Legs Connector
5 Legs

Assembly

Glue \ Press fit inserts into frames.
I used Vellum paper as the inside backing to diffuse the light. You can print and use either of the inserts for light diffusion as well.
Stick printed inserts or vellum paper to the inside of the frames.
Glue all frames together using alignment keys and keeping the bottom side open.
Finish led work or pendant lamp before inserting the bottom insert. I used pendant light wiring kit myself.
Lastly attach the bottom panel. I used tacky craft glue to attach the bottom panel to be able to take it off if I need to change the bulb.

Astonishing looking model! Was in search for a bedside lamp, so scaled this one down to 70% (even smaller would probably lead it to be too flimsy). I'm still improving my LED work, but wanted to get a photo done. Printed with Amolen wood PLA and some plain white PLA. Thank you for this great design!

Thank you very much for photos and kind words. :)

Printed extremely well. It's a lot bigger than it looks. each side has 3 pieces if you print the screen which I did. Each piece has to be printed 1 at a time because of size. If I do it again I will scale it down just so I can print multiple pieces at once. I use Bambu Silk Copper PLA, Flashforge Burnt Titanium Petg, and Overture Transparent Clear Petg.

Take your time building. If one side isn't aligned then it throws off the entire build. I suggest printing all your parts then build all 12 sides. I built 11 as I wasn't sure how I was going to build the base or lighting until the end. Then assemble the sides together. I also suggest clamps to hold while drying. I wouldn't use activator as you need to make sure it's completely aligned. Another tip, I didn't have great success with the alignment pegs. They seemed to large for the sides to be flush. I ended up cutting them in half and then after gluing one in place I filed it down so the connecting side would sit flush. Printing the clear screen is also delicate. I ripped a couple taking it off the bed. I only printed them at 1 layer but you could go 2 or 3. Test the light diffusion with the type of filament you use

Slightly awkward to assemble but it's gorgeous

der Druck sieht schon mal mega gut aus. Ich konnte die Lampe aus Platzmangel noch nicht zusammenbauen, da sie größer als erwartet ist. 😬

Very cool! I don't know if you're into sci-fi television shows? But I was watching the "Foundation" show on Apple TV recently, and one of the devices that plays a big role in it is what they call the "Prime Radiant" -- a supposed supercomputer that allows predicting future events on a large/macro scale. It's in the shape of a cuboctahedron with some interesting lattice-work on the inside faces. I really wanted to try to 3D print a replica of it, but realized the existing print files for a cuboctahedron, even printed with a colored "glass" type filament, don't get too close to the TV show's prop because they seem to have the intricate inner part as a frame that the clear outer shell goes around. Anyway - your lampshade here comes closer to the idea than anything else I've seen so far, except this one guy who made an amazing replica (but didn't share his print file or much info on how he accomplished it), here: https://www.therpf.com/forums/threads/foundation-prime-radiant.353785/

Hi Tom, I haven't watched that show but the replica sure looks cool. You've definitely given me great inspiration. Thank you very much for that really.

@synaptic.axon

I have modeled the Cuboctahedron a zillion times in Fusion360. Best bet is to start with a cube, then draw lines between every line midpoint to the nearest neighboring midpoints. Also a big fan of the Stella Octangula (dualed Tetrahedrons, eight of which stack for a Cuboctahedron). I've watched Foundation and also noticed the cuboctahedron. Just need the "innards". I suspect you could also embed some small displays, microcontroller, and touch gesture sensitivity so it actually works. :) Empire! btw - I named a cat Cleon I.

I don't see the: - Frame with Hole for LED Strip Wire - Insert Pattern - For E26_E27 Pendant Lamp - Insert Film - For E26_E27 Pendant Lamp (Pattern 1 or Pattern 2) - Stand Top - Legs Connector - Legs in the provided print data. Am I missing something or did they get lost?

I found them: https://www.printables.com/model/612108-dodecahedron-lamp/files

@JalShah

They are available here as well. Click on RAW model files and you will see those.

Replying to @JalShah :

Ah alright, thanks a bunch. Somehow missed that. Just in the midst of building the lamp. Thank you for the design!

@olievc

very Nice

I can add the link in description, if you'd like. Please let me know.

@user_725397904

What kind of glue did you use? I have tried two types but they seemed reluctant to hold. The print and design are perfect! I may do a remix on it...

@mtvlabs

Bob Smith CA glue with an activator spray.

@FatalFallacy

I just used plain universal craft glue, but with a lot of small craft spring clamps attached to get enough pressure on the parts during bonding and settling, panel by panel.
