3d box made from 1/4" MDF on my ShapeOko CNC

Replacement for the standard "spindle mount" that comes with the shapeoko builder's kit.

NEMA 17 Mount for Shapeoko CNC

A light-weight slide for running on Rexroth (Bosch) 40x40 extruded aluminum.

This is a fully printable eggbot, which was inspired by the original Eggbot as well as the other designs by Zaggo and Berserker.

I designed this one to be complete, and fully printable. And easily assembled. Also all parts are no larger than 100mm in any direction so should be printable on any 3D Printer out there. Lastly I wanted to keep the amount of plastic used to a minimum where possible.

It's intended to be printed in PLA on my Ultimaker.

It's unfinished in that I haven't printed it myself to test it. Normally I don't release things until they are "done" but since Easter is coming up fast, I thought I better get this one out there so hopefully some others can build one in time. I'm hoping to make mine this weekend, and will post pics once it's assembled.

It's intended to be used with the spherebot electronics and firmware. thingiverse.com/thing:7656

Hope you enjoy!

EDIT April 2 2012:
I've refined some of the parts. Updated STLs are uploaded. The Egg cup parts didn't work out as planned, replaced them with suction cup based ones. Also I strengthened and thickened up the Back Plate part as it was a little flimsy (still works in it's original form, as I left it on mine, but I figured it could use some strengthening for general use).

EDIT April 4 2012:
Ok another minor revision to a few parts. I've uploaded the new designs now. Also here are some pics of the finished build. I'm still just wrapping up the electronics. The changes I made were shortening the egg cup holders to allow for a larger egg to fit, and I had to adjust the arm pivot to allow the motor shaft to protrude through it. You will need washers on those screws now but it will allow a better depth adjustment for the pen to allow it to center up nicely on the egg (keeping the image from skewing when you print it).

This is my printer. Derived/inspired by the Aluminum Mendel. I wanted to make a printer with extrusions that was larger than the normal 8 x 8 platform. I liked the Aluminum Mendel design very much but wanted to scale it and change a few things.

Here is what I did:

nearly 12" X 12" X 12" build envelope
10 mm smooth rod on X and Y axis with LM10UU's
NEMA 23 for Y axis
Carriage for Greg's hinged accessible extruder
I disassembled an ATX PSU and mounted it with Gen 7 under the build platform
I plan to redesign the x ends to accommodate springs in case of crash so I can remove the springs from under the build platform to reduce jitter.
and many other parts I redesigned

I have this up and running and will post more files soon.

An updated version of the MendelMax 3d Printer. Nearly every printed part on the bot has been updated to make the assembly easier and faster and the printer more accurate.

Major upgrades include easier to assemble lower vertexes, Lower mounted Z motor mounts, an improved Y axis belt tensioner system, and easy to align Z axis smooth rod mounts.

NOTE: While I do not consider this a work in progress, it is still not widely tested. I recommend this design even for new users, but if you prefer a rock solid well tested design you may prefer the original MendelMax.

This is called an ORDish Bot instead of ORD Bot because it's bigger than the Quantum or Hadron ORD Bots, and it's built with generic MakerSlide wheel carriage plates instead of parts made specifically for the ORD Bot.

9.75" x 11" build platform
Nema 17 stepper motors
MakerGear Stepper Plastruder

This printer won't quite fit in your pocket, but it is very easy to take with you. I designed the printer around two constraints. First, the high mass motors and extruder are stationary. This allows smooth high speed printing, as only the print bed moves. This keeps the forces on the slides low as well. This will also allow dual extruders on a very lightweight printer. Second, the slides are all integrated, using PLA bearing surfaces running on the extrusions. I wanted to try this on all the axes of a printer since it works so well on my Aluminum Mendel. It is self-contained, with power supply on board. It is very robust, and makes top quality prints. I made this printer to test the above constraints, but it works so well I decided to publish it.

The print volume is 120mm W x 100mm D x 65mm H. This could be expanded a little by getting longer extrusions.

I posted a video at youtube.com/watch?v=4tpOokI6_Z0
I wanted to see if it could print vertically. It is printing a stretchy bracelet - thingiverse.com/thing:13505.

I hope this inspires others to expand on this design.

This is a DLP projector-based resin printer that can make very fine 3D prints in record time.

This is a work in progress. Today I plan to begin actual experiments with the resin.

I believe the basic design I am producing here is very suitable, however, the details of the design need changes in almost every part to be ideal. Most importantly, the vat should probably be much shorter, but the whole thing could be made significantly smaller.

I am currently using resin from
Bucktown Polymers:

bucktownpolymers.com/

(You might notice their price for resin is cheaper than some current PLA prices, by volume)

A2Sheds has provided a page with a few helpful resources, as well as the beginnings of his own DLP project:

code.google.com/p/lemoncurry/wiki/main

This is very much a work in progress. Expect more photos and videos to come.

Here's a link to my flickr site documenting this project:

Next steps: Experiment with resin. Create working software stack.

Known Issues: Vat is too tall/big, glass may be too weak/thin. Vat probbaly needs a nonstick coating, like silicone or PTFE. Z Axis range is 5", vat is 5", so Z stage cannot quite clear the vat. A2Sheds recommends a heated vat to 50c so the resin flows better...

UPDATE: A New updated version of MendelMax is available at thingiverse.com/thing:20355. It is recommended for all new builds.

MendelMax is a new RepRap 3d printer designed by Maxbots. It is a true reprap, using printed brackets, but instead of using threaded rod for the structural elements it uses inexpensive aluminum extrusions. This gives a huge increase in rigidity for a minimal extra cost (Self sourcing will cost about $50 more than a standard Prusa when purchased from the recommended suppliers). The required extrusions are available world wide from a variety of suppliers.

In addition to greatly increased rigidity, this design is faster to assemble (probably 4 hours for most users), easier to print, has a larger build volume (~215x235x190 if built at the standard dimensions), and is easier to hack on.

Update 2/7/2012: MendelMax full kits and hardware only kits are now available from Maxbots (aka Kludgineer on Thingiverse) @ store.mendelmax.com!

Fully Automatic

With the automated build platform it will keep printing and printing.

The automated build platform is truly a revolution in 3D printing. It allows you to have a print queue where your machine will clear the build surface between builds and print objects one after another. This turns your MakerBot into a little factory that sits on your desktop. Best of all, this is completely automated: you hit print, and the machine does all the work. Want to print 100 butterflies? Easy. Want to print an entire chess set? No problem. Want to start a business selling printed things that you've designed? Awesome. Have the bot do all the work while you design new things.

Extremely Reliable

The MK5 plastruder will give you thousands of hours of trouble-free printing.

We've invested many hours into designing, testing, and tweaking the MK5 plastruder. The result is an extruder that is extremely reliable, and very simple to maintain. The hot end on this extruder is essentially unbreakable and the filament drive system is one of the strongest on the market. We've run these things for thousands of hours with minimal problems. Changing the filament is a breeze with the filament pressure thumb screw. You can even swap the filament while the extruder is running if you're fast enough.

Higher Quality

The layer alignment is much better which results in nicer prints and higher resolution.

We've completely overhauled the drive system to give the optimum positioning accuracy. The entire system has been upgraded to sturdy 3/8" diameter linear shafting. This is probably overkill, but you can trust that the axes will be sturdy. We've also switched to self-aligning, sintered brass bearings. These are very forgiving to DIY assembly and provide a nice, smooth motion on the steel shafts. Last, but not least we've completely replaced the Z axis with a stepper driven, cantilevered stage. Guided by two of the linear shafts, this completely eliminates any Z wobble and results in nicely aligned layers. Using a high-angle lead screw, we were able to increase the speed of the Z axis from 150mm/minute to 1000mm/minute. This means the layer changes are almost completely imperceptible and reduces blobbing significantly.

Easier to Use

Connect over USB and hit print - the machine will detect its position and start printing.

The new electronics have been designed to make the printing experience even easier than ever. The motherboard now sports an integrated USB port, so you simply plug the MakerBot in with a standard USB cable. We've also added full endstop support so that you never need to touch the XYZ axes ever again. When you hit print, the machine will automatically home itself, heat up, and begin printing. All you have to do is sit back and relax while your MakerBot does all the work. Living in the future is awesome. Oh yeah, and the electronics are all inside, so you don't have wires dangling everywhere.

This is the Quantum ORD Bot. It is 3D printer mech platform made from MakerSlide linear bearing. It is extremly ridged and very easy to build. The design can easily be scaled in X,Y and/or Z by simply changing the Makerslide lengths plus belt and leadscrew lengths. This is the mini or 'Quantum' version. The parts other than MakerSlide are either off the shelf standard items or easily fabricate with a laser cutter, 3D printer or CNC router. There is a blog post giving a lot more detail.

buildlog.net/blog/2012/01/the-quantum-ord-bot/

As a reference point, this size uses less than $15 worth of Makerslide extrusion. You also need about $45 worth of MakerSlide wheels, spacers, etc. The Makerslide parts are available at the MakerSlide store. Be aware the rail is released in weekly 'production batches' and sells out very quickly. It is 'restocked' on weekly basis.

I have attached the complete 3D design in STEP format plus a DXF of the flat parts. If I can generate enough interest, I may have about 50 sets of parts fabricated and offer kits. That would be for the mechatronics platform only. The extruder, electronics, etc would not be included.

Why spend $200 for a set of printed parts when you can have everything you see here, including motors, belts, pulleys for about $200?

Planned changes.
1. I plan to change the crossbar handle thing to an extrusion to make it more scalable.
2. The 'quantum' design currently uses NEMA14 motors. I plan to tweak the parts to be compatible with NEMA17. This just adds a second pattern to some parts.
