With the easy availability of cheap and 3D printers from the usual Chinese websites, you might think that there could be little room for another home-made 3D printer project. fortunately, the community of 3D printer making enthusiasts doesn’t see it that way.
[Bobricius] has a rather nice 3D printer design in the works that we think you’ll like. It follows the MakerBot/Ultimaker style of construction in that it is a box rather than a gantry, and it is assembled from CNC-cut aluminum for a sturdy and pleasing effect. Whar sets it apart though is its size, at only 190x190x251mm and with an 80x80x80mm print volume, it’s tiny. You might wonder why that could be an asset, but when you consider that he already has a much larger printer it becomes obvious that something small and portable for quick tiny prints could be an asset.
Unusually for a home-made 3D printer, it has no 3D printed parts, instead, it is laser cut throughout. And also unusually all the CAD work was done in EAGLE, better known for PCB work. It’s a work in progress we’re featuring today because it’s a Hackaday Prize entry, but it looks as though the finished item will be something of a little gem.
Homemade 3D printers can be particularly impressive, for example, we’ve shown you this excellent SLA printer.
The concept of self-replicating 3D printers is a really powerful one. But in practice, there are issues with the availability and quality of the 3D-printed parts. [Noyan] is taking a different approach by boostrapping a 3D printer with laser-cut parts. There are zero 3D-printed parts in this project. [Noyan] is using acrylic for the frame and the connecting mechanisms that go into the machine.
The printer design chosen for the project is the Prusa i3. We have certainly seen custom builds of this popular design before using laser-cut plywood for the frame. Still, these builds use 3D-printed parts for some of the more complicated parts like the extruder carriage and motor brackets. To the right is the X-carriage mechanism. It is complicated but requires no more than 6 mm and 3 mm acrylic stock and the type of hardware traditionally associated with printer builds.
With the proof of concept done, a few upgrades were designed and printed to take the place of the X-axis parts and the belt tensioner. But hey, who doesn’t get their hands on a 3D printer and immediately look for printable solutions for better performance?
We first saw a laser-cut RepRap almost nine years ago! That kit was going to run you an estimated $380. [Noyan] prices this one out at under $200 (if you know someone with a laser cutter), and of course you can get a consumer 3D printer at that price point now. Time has been good to this tool.
Back in 2014 [Johan] decided to celebrate BASIC’s
30 50 year anniversary by writing his own BASIC interpreter. Now, a few years later, he says he feels he has hit a certain milestone: he can play Flappy Bird, written in his own version of BASIC, running on his own home-built computer, the BASIC-1.
Inside the BASIC-1 is an Atmel XMega128A4, a keyboard from a broken Commodore 64, a joystick port, a serial to TV out adapter, and an SD card adapter for program storage. An attractively laser-cut enclosure with kerf bends houses the keyboard and hardware. The BASIC-1 boots into BASIC just like many of its home computer counterparts from the 80s.

This little DIY 64×64 graphical printer by [Egor] is part pen plotter in design, somewhat dot matrix-ish in operation, and cleverly designed to use unmodified 9G servos. The project page is all in Russian (translation to English here) but has plenty of photos that make the operation and design clear. Although nearly the entire thing is made from laser-cut wood, [Egor] says that a laser cutter is optional equipment. The first version was entirely cut with hand tools.
Small DIY CNC machines driven over a serial line commonly use Arduinos and CD-ROM drive guts (like this Foam Cutter or this Laser Paper Cutter) but this build uses its own custom rack-and-pinion system, and has some great little added details like the spring-loaded clip to hold paper onto the print pad.
The frame and parts (including all gears) are laser-cut from 4 mm plywood and the unit is driven by three small servos. A simple Java program processes images and an Arduino UNO handles the low-level control. A video of everything in action is embedded below.

[Ryan Bates] loves arcade games, any arcade games. Which is why you can find claw machines, coin pushers, video games, and more on his website.
We’ve covered his work before with his Venduino project. We also really enjoyed his 3D printed arcade joystick based off the design of a commercial variant. His coin pushing machine could help some us finally live our dream of getting a big win out of the most insidious gambling machine at arcades meant for children.
Speaking of frustrating gambling machines for children, he also built his own claw machine. Nothing like enabling test mode and winning a fluffy teddy bear or an Arduino!
It’s quite a large site and there’s good content hidden in nooks and crannys, so explore. He also sells kits, but it’s well balanced against a lot of open source files if you’d like to do it yourself. If you’re wondering how he gets it all done, his energy drink review might provide a clue.
[Fuzzy Wobble] and [Amy Wang]’s Deep Space Settlers project is a one-of-a-kind re-invention of the popular board game Settlers of Catan, and showcases the polished results that are possible with the fabrication tools and methods available in many workshops and hackerspaces today. We reached out to the makers for some of the fabrication details, which they were happy to share.
(For those of you who are familiar with the game, technically this is a remake and slight evolution of the Seafarers expansion to the base Settlers of Catan game. A few rule changes were made, but it is mostly a total remodel and redesign.)

In what might be one of the coolest applications of laser cutting, joinery, puzzles, writing, and bookbinding, [Brady Whitney] has created the Codex Silenda — a literal puzzle book of magnificent proportions.
[Whitney] had originally conceived the idea of the Codex for his senior thesis research project at Iowa State University, and the result is something for almost everyone. On each of the Codex’s five pages lies a mechanical puzzle that must be solved to progress to the next, while an accompanying text weaves a story as you do so. These intricate pages were designed in SolidWorks and painstakingly assembled from laser cut wood. Breaking the fourth wall of storytelling by engaging the reader directly in uncovering the book’s mysteries is a unique feat, and it looks gorgeous to boot.
