Massive Mural from Thermal Receipt Paper

Receipt paper mural from above eye level

Turning trash into art is something we undoubtedly all admire. [Davis DeWitt] did just that with a massive mural made entirely from discarded receipt paper. [Davis] got lucky while doing some light dumpster diving, where he stumbled upon the box of thermal paper rolls. He saw the potential them and, armed with engineering skills and a rental-friendly approach, set out to create something original.

The journey began with a simple test: how long can a receipt be printed, continuously? With a maximum length of 10.5 feet per print, [Davis] designed an image for the mural using vector files to maintain a high resolution. The scale of the project was a challenge in itself, taking over 13 hours to render a single image at the necessary resolution for a mural of this size. The final piece is 30 foot (9.144 meters) wide and 11 foot (3.3528 meters) tall – a pretty conversational piece in anyone’s room – or shop, in [Davis]’ case.

Once the design was ready, the image was sliced into strips that matched the width of the receipt paper. Printing over 1,000 feet of paper wasn’t without its issues, so [Davis] designed a custom spool system to undo the curling of the receipts. Hanging the mural involved 3D-printed brackets and binder clips, allowing the strips to hang freely with a kinetic effect.

Though the thermal paper will fade over time, the beauty of this project lies in its adaptability—just reprint any faded strips. Want to see how it all came together? Watch the full process here.

My first display piece I'm actually proud of

My first display piece I'm actually proud of

Inspiration came because christmas is coming up and i needed a gift for my dad. Mom and brother are getting a moon and deathstar lamp respectively. My dad loves sailing so i came up with this. Designed in onshape over the course of four days. The sails were a bitch but im glad i got it figured out. Anyway let me know if theres interest in stl's. Final version will have some changes for easy of assembly.

Help with structure longterm resistance - Resin Print

Hello all,

My wife made this design and we got a resin 3D printer to print it.

Her 3D designer friends are saying that the top will bend forward with time. As you can see, it is a 40cm tall piece with a thin support.

We planned for the balance by making the base solid resin and the bodies hollow. However, we are looking for methods to guarantee that the top part will not bend with time. It is also worth mentioning that the print will be made out of 3 parts (at least) and glued together, and my wife does not wish to change the visible design (so it can stay true to the original sculpture).

This will be our first macro printing, so any advice is appreciated. Thank you in advance.

Arduino/Electronics Enclosures

Arduino/Electronics Enclosures

I've designed a bunch of these enclosures for various arduinos and other components. There are more not included in this photo (because they need a bit more refinement).

There's still some room for minor tweaks and improvements but I'm fairly happy with them so far.

Which of the 3D printing sites should I post these to? Which ones do people still use? Printables, Makerworld, Thingiverse? And does anyone aftu

I use makerworld most often due to having Bambu printers. I've read people aren't huge fans of thingiverse anymore, so should I even bother posting to there?

I'm thinking makerworld and printables are the no brainers.

I also only want to post them if people actually want them because I've got a lot of projects under way and not much free time.

So let me know if you think it's worth the effort to post them based on whether or not you'd like to print them.

The cases in the photo are for: - Arduino Uno - Arduino Nano - 1602 LCD - OLED display - LM2596 Reg with Voltmeter - XL4015 Reg with Voltmeter

They will be free to use for anything non-commercial but I might allow people to sell them for some kind of license fee, which can contribute to the never ending cost of filament I rapidly churn through.
