Description

Modular Infinity Cube – Perfect Hinges

After countless iterations and a lot of dedication, I’m proud to share my final design for the Modular Infinity Cube.

Unlike most infinity cube designs, this is not print-in-place—and that’s intentional. By assembling it post-print, this design completely eliminates hinge imperfections, offering a smoother, cleaner, and more satisfying movement than typical models.

The STL and .3mf files include optimal print orientations for best results.
There are three custom parts included to assist with easy and accurate assembly—no special tools required, just a stable surface.

Be sure to follow the instructions below and watch the assembly video to get the best results.

Assembly Guide

This guide explains how to assemble the Modular Infinity Cube.

There are a total of eight (8) hinges that must be manually assembled. Each hinge piece is labeled with a number. Align the matching numbers together (1 with 1, 2 with 2, and so on). Then, use the Upper Bracket, Lower Bracket, and Press Cap to press the hinge pieces securely into position.

Important: The numbers must be positioned next to each other — not opposite or misaligned! Thanks to its modular design, you’re not limited to building the standard cube.

Feel free to create a setup with just 4 cubes, or even expand to 16! Sky’s the limit!

Correct Orientation — correct number alignment

Set the correctly aligned cubes on the Bottom Bracket.

Add the Top Bracket on top of the cubes with the opening hole above the correctly aligned Hinge.

Put the Hinge Piece into the hole. Next the Push Cap will be used.

Put the Press Cap on top of the Top Bracket. It should slot in easily.

Push the Press Cap down.
**Push uniformly, on a stable surface and with a lot of force. If done correctly there will be an audible click.**

Repeat this process for all 8 hinges. The order doesn’t matter, as long as you correctly align the numbered parts.
A helpful approach is to start with all the odd-numbered hinges first, followed by the even-numbered ones.

Printed with Elegoo PLA. The rounded corners on the underside came out warped. Rest of it look fine. It works, with a bit of resistance. Do you maybe have any tips to improve the bottom side corners? I printed with 210°C and the speed settings in your profile. And I changed infill to 10%. Picture is the same cube, camera was a bit fighting with the white balance ;)

@VertLV

Thanks for the feedback! I’ve had similar issues with bottom edges on certain filaments. From my experience, it's usually due to printing too hot and too fast. My profiles are tuned for Bambu PLA, so ELEGOO PLA may not perform the same. In Bambu Studio, try adjusting the filament settings: Temperature: Use results from a temperature tower test Speed: Print in 50% speed mode The settings in the images are in German, but their positions are identical in English. I recommend printing a 2×2 cube at each temperature to find the sweet spot. If these changes don’t help, likely noting will—I wasted 1kg of Prusament fine-tuning mine. Bambu’s "smart" features like auto extrusion, speed, and cooling—often unchangeable—can sometimes make things worse. Cura worked flawlessly for me at slow speeds (50mm/s), but it’s risky with Bambu printers, so I wouldn’t recommend it.

Replying to @VertLV :

ok, thanks for hints, I will try again with reduced speed and temp (i am using Orca). If that doesn't work I will try with some Bambu PLA ;-)

@VertLV

Replying to @chrismaddahl :

You are welcome! You can also try the chamfered edges version, it comes out better more reliably.

interesting Idea! if you get it right the first time it is awesome, if you put it together wrong like I did, it has PLA issues on the second assembly. I printed out several and they all move great. the tools help to put everything together. assembling multiple in a row, I stood on the tool to save my hands.

@VertLV

Thanks for the positive feedback! Standing on them was a smart Idea, when I assembled 5 of them in a row, it was pretty hard on my hands.

@Nocho

Replying to @VertLV :

I forgot to mention, I printed them at 80%. still came out great!

@VertLV

Replying to @Nocho :

Another good idea! I really enjoy the premium feel the heavier cube gives you.

Difficult to put together, strength-wise, but it sure does look amazing!

Thanks for the feedback! I am glad you enjoy it. Sadly if you make it easier to put together it looses a lot of strength for normal use.

FANTASTIC!!!! I'm printing them in series. Since I got the first one, my children keep asking for more, and even more to give to their friends. Excellent design. Congratulations again.

came out well after i figured it out. printed 8 more to make a multicolor one. Will attach a picture when that one is done. now that it is done i have made only one mistake. but still came out really good in my opinion.

okay i feel silly, but when i try and do the even's they are backwards to each other. What am I doing worng?

@VertLV

Hey, thanks for the comment. This is not a problem. As long as the numbers are next to each other it is the correct alignment. I hope you will enjoy your Cube!!

@JBPS

Love this print… Had to post the latest creation. The purge waste on this one got a little out of hand 😂

excellent print and instructions. No more splintered hinges! Printed in ABS and it still snapped together perfectly. (Definitely do it on a firm surface)
