Discover our unique DIY project that blends creativity, utility, and sustainability. This guide will take you through the construction of a LEGO display box, ingeniously crafted using offcuts of V-SLOT aluminium profiles and OpenBuilds accessories. Not only is this an eco-friendly approach to reusing surplus materials, but it also results in a stylish, functional display for your prized LEGO models. Whether you're a LEGO enthusiast or have little LEGO fans at home, this innovative project offers

Using most of the parts of the MiniMill, and adding a few other parts (cost < $200), transforms the MiniMill into a very capable machine. Final build area as shown is 10.25" x 16". With a custom Y-plate, I will take it to 10.25" x 20-24".

The Tiger Paw will be a 1000mm X 500mm Cartesian style CNC with the Minimill attached to the end. It is named the D&R Tiger Paw because my son, Daniel, and myself, Richard, will put this Tiger strong and fast machine together. Our goal is to have a Tiger strong build with a Paw print that wouldn’t take up a huge amount of space in our garage.

The Ooznest OX CNC Machine Kit is based on the OX CNC Machine designed by Mark Carew, and it incorporates many upgrades from this community. The plate designs in our kit are based on the originals. However we have added our own touches to increase the performance and design of the machine. To complement Mark's build videos, we have made a complete written instruction manual, with IKEA'eske assembly diagrams.

A lightweight, portable, accurate 3D Printer that has a good sized print area and small overall footprint that is easy to build, with easy to source components. The design is OpenSource allowing those with the capability to make their own parts get up and running.

I'm conducing guitar loudspeaker cabinet fabrication technique research (material type/thickness, mechanical joints, adhesives, etc) and how these relate to cabinet/speaker coupling and enclosure resonance with respect to psycho-acoustics. Basically, does one speaker cab sound better than another and why?

We are introducing the Cairo Mini 3d-printer! It’s a DIY fully Open-source Reproducible 20x20cm 3d-printer. The original goal of the Cairo Mini 3d-printer is to create a low-cost 3d-printer below 220$(3500 LE). That anyone can build with ease.

A table top OpenBuilds MiniMill build. 48V 52mm spindle with ER11 collets.

This is a rework of a previous build I did on here, a mostly printed cartesian CNC. Initially intended to just be an update to that, but so many things changed including the linear motion and every single part has been modified significantly that I felt as though it deserved a whole new build.

Super solid core xy build inspired by the e3d tool changer

This is the build of a cartesian 3d printer made of an old Anet and Geeeteck, some 2020 alu profil and linear rail. Powered by a Rumba with a Nextion screen. It should be modular and accept dual Extrusion and laser engraving.

I have been working on this project for something like 3 years on and off, sometimes leaving it for a few months. Now I really want to finish it. For me, the mechanical part was the easy (though long) part because I get to use about 17 CNC machines and MasterCAM and I am a machinist. The hard part is the electronics part. Had a few problems getting Windows to communicate to the X5 Mini via the USB cable but found something on the Smoothie forum and got the machine moving.

The C-Beam Evolution is an evolving machine. The MkII is inspired by Kyo's C-Beam Spinx but currently uses my own design of plates made of 8mm acrylic (X-axis ends) and 6mm polycarbonate (Y axis ends). The plates were made on the MkI but I hope to be able to make 6mm aluminium plates on the MkII for the MkIII.

The new MiniMill from Mark and Sonny is a great little machine.

Another MiniMill, different to the OpenBuilds version and potentially more flexible because of the design.

I will post soon some more details.

Next up will be the electronics package. My parts bins are overflowing with boards so this may be the hardest decision to make of the entire build.

All-in-one OB Minimill

This is my first build and I've been waiting to do this for a very long time.

I am building a simple home brewed printer. I have a background in industrial automation so I figured how hard could this be. The mechanical build was pretty smooth as was the electrical side. Now just getting plastic out the hotend is my stopping point.

CNC Mini Mill build with some mods after following standard build on Youtube video.

I ordered the OpenBuilds MiniMill from the OpenBuilds Parts Store http://openbuildspartstore.com/ They were out of Motors and Electronics when I ordered so I had to source these items elsewhere. But it turned out well doing it this way.

Some enhancements of the basic mini-mill

I put this together to cut aluminum. Chips get everywhere! Cover your lead screws. Put the mill inside an enclosure. DON'T mount electronics (especially the power supply) inside the enclosure, chips will get into it and short it out. Remove the manual jog wheels, they contribute to chatter (something about having a mass on the end of the lead screw causes vibration). I cut at 14000 RPM, 0.05 inch width of cut, 0.05 inch depth of cut, 30 inches per minute and just barely avoid chatter.

I really like the 4th axis I purchased a few years back, but when I went looking for it again the suppliers who once carried it no longer do. Anyone know who makes it? Center hole receives collets. I own a ShopSmith so I am using a 5/8th rod and can mount it's chucks onto this machine. Also I like the use of the skateboard wheels, they are adjustable and one could use more sets over a longer axis. The Sherline z-axis is not my first choice, I just had a spare.

This is a slightly-modified OpenBuilds minimill with some more Y travel and a v-slot table.
