This is my entry for the Atomstack contest- the newest (and cutest) Atomstack laser cutter. It has many improvements over previous Atomstack engravers, such as only using 3d printed parts, being very cheap, being very small (portable), and energy efficient, easy to assemble, and more! All at the minimal cost of not working. But what's this? It does work! Albeit only being able to cut one design (the Atomstack logo, so you couldn't ask for much better than that.), and being fully manual, this fully 3d printed laser-free cutter works! It also looks cool, is fun to play with, includes a free bonus puzzle, and fits on the palm of your hand! The cuttable sheet/bonus puzzle can also be printed with a color swap to make it look more like a real laser cut piece.

You can also 3d print or laser cut your own designs if you want, the dimension of the sheet are 85.344 mm front to back by 89.611 mm side to side. The measurements are weird because of the way I designed it.

-To Use the Cutter
First, print and assemble it.
Then, print the sheet, flip it over and put the pieces in.
Next move the cutter head to the front and flip the whole thing over, tilt it so you can
put the sheet in above where the head is, in the guide rails, holding it with one finger while you level the cutter, then hold it in place while you flip the whole thing over. I would include pics but it his hard to take pictures of upside down.
After you have done that, the cutter is ready to go! Just move the bed back, optionally moving the head for maximum fun, and watch your hard work on the puzzle be transformed into something beautiful.

Another idea is that you could print the sheet really thin and tape a piece of paper to the bed, which might be easier to use.

Print parts, painting is optional.

Take the bed/x axis, and the top section/y axis and align the clips on the top part of the rails...

... then push forward

Take the base and align the front two clips and clip them in...

...move the bed to give room...

...and clip the back together.

take the cutter head and the window, and bend the window slightly, then shove it up to the top behind the front wall. This is kind of tricky sometimes, but if you have problems you can just glue it

the e-stop button is pretty self-explanatory, but if you align the seams, it may stay in better.

Take the cutter head and place on the x axis rail at a slight angle...

...then push down and slightly forward to clip.

Enjoy!

The original concept was one of a few and seemed out of all my ideas like the most doable, while still having some uniqueness.
I designed this using Fusion 360 and printed with a bambu lab printer. It took several hours per piece to design, including several revisions. The part that was the hardest was the sheet, I had to redesign the whole thing because the original had a grille that had cubes with slots, which made the whole thing very low-res and didn't have enough tolerance to work. I then had to modify the redesign because I kept printing it slightly too wide to fit in the top, and the pieces had too little tolerance. the logo was also hard to add, and the unique shape of the control panel, as Fusion is very picky about importing svgs, so I had to trace much of it by hand. The cutter head also had to be redesigned, as the original was too long and hit the sheet, and the clip was too short and didn't hold it on. One part that I luckily found out early on was how I was going to be able to put it together. Overall I would say that I am pretty satisfied with the end result, although I would like to have been able to include more designs and a quicker way to reset.
