This ninja star was modeled on Autodesk Inventor Professional 2012 and printed on the Makerbot Thing-O-Matic using 3mm plastic filament. I created design because i wanted to make something that served a cool and interesting purpose. Rather than making a useless figurine, i decided to manufacture a functional ninja star. I started by making this design in Autodesk Inventor and used the chamfer tool to make the blades of the star, which were made very thin. The point of this was to test how thin the Makerbot Thing-o-Matic could print. As it turns out, the makerbot did not print very thin. Also, the thinnest layers were very weak. What I would do differently next time is not to make the blades as thin. I would keep them thicker to make it stronger. Also, I would make the fill 100% because the ninja star could be a little bit heavier.

Wanted some visepads that would allow me to grab a PCB more easily. I have a helping hands, but that's too small for doing multiple piece batches. These pads are smooth with a 2mm channel near the top

Overall width: 110mm
Space between holes: 60mm
Hole dia: 6mm
Hole cap dia: 10mm
Hole countersink depth: 5mm

Functional Pin Tumble lock. All of the components can be printed with the exception of the helix compression springs. These springs can be taken out of standard click pens. The springs I made this for are 4mm OD and ~20mm long.
I made a small window in the "Outer Barrel" to view the key pin pushing up on the driver pin.
This was a quick project to familiarize myself with the design constraints required for successful FDM designs/prints. I thought I would distribute since it could be fun for teaching and demonstrations.

I think we can all agree, life would become much more interesting if I launched a turtle shell at you every once and a while.

But it’s no fun if I’m the only one with a shell to launch. Therefore…

Turtle Shells for Everybody!!!

All you have to do is print it out and assemble!

The Turtle Shell Racer is as fully 3d printable as I can make it using my Makerbot Cupcake CNC and its MK5 Extruder. The pdf file contains full assembly instructions and a parts list. This is a very ambitious project; expect to spend some time on it.

UPDATE Sept 26th

I have uploaded the modifications I made to the shells for the NYC Maker Faire.

Wheely Bar.stl - This replaces the rear axle brackets.stl with a wheely bar, which allows awesome wheelys!

New stearing Link.stl - This new link replaces the old steering linkage.stl. It is designed to capture one of the servo horns and allow a better connection between the servo and the steering.

We have a pole that allows us to reach our attic ladder, and I wanted to create a bracket so I could mount the pole inside a closet. The pole is roughly 31 mm in diameter.

I designed the bracket from scratch using Sketchup.

I added supports to the arms to assist in printing. Once printed, these break away easily.

Around the nozzle cooling for 5x5cm fan for building small prints!

Little vertical wind mill. Can be mounted e.g. on a motor axis and fixed using a screw. STL is for a 2mm axis and M4 screw + nut, but that can be changed in the OpenSCAD script.

As I went to open my blind in my bedroom one fine day, the left bracket exploded and the blind fell on my head. These are the cheap, Walmart style blinds that were never really designed to last, I imagine, but in any case, it seemed stupid to buy new blinds than to just make a new cap. So this is that.

this is a skull i modeled in sensable freeform then surfaced and exported to solidworks.

So this was be SplitReaction’s first project at Maker Faire 2010 NYC. We wanted to wow the crowd and build something awesome, a project that would inspire kids to become makers and engineers. Also it had to be fun to build so of course the best thing to do was to build a 10 x 10ft Mega Claw Game.

A claw game would be challenging since it would have plenty of electrical work, construction and a lot of ideas to present at the fair and for the blog. It would also be tough because we wanted to build it bigger than anything we’ve ever worked on, ten feet by ten feet to be exact.

I hit the store to buy a ceiling mount for my Optoma HD66, but the store was out of stock. So I designed up this one, and printed it out. It's designed specifically for the HD66's slightly odd 100 x 100 x 110 mm triangular M3 mount, but a redesigned ProjectorPlate.stl will let you stick any projector on there. Swivels in XX, YY and ZZ, and is fairly stable too.

Give your iPhone a 1-up! I designed this for my fiance, who wanted a fun charger for work. I based the design from a candy tin she bought at a shoe store (of all places) that was approximately 75% the size required.

I've always been a last minute Christmas shopper and it has usually worked out. This year I had a request to get a Connect Four game, but I couldn't find it in stock anywhere. So I decided to make my own version of it.

After working like one of Santa's Elfs for a few hours (minus the green tights) I had beautiful Connect Four style game.

Since I am giving a presentation at a conference with the subtitle "Here be dragons" I knew I had to print dragons.

I've managed to cut the head off the open dragon from here:http://www.cgarena.com/freestuff/meshes/meshes.html

But it's not a clean cut and I'm not terribly good at editing models so if someone wants to improve the cut, I'll reupload the model.

Update! Nate True fixed up the model. I've added a second file called "dragonheadfixed" that you'll want to use from now on. Thanks Nate!

I cleaned up the hand and made it suitable for printing on a makerbot. Its smaller and I removed the hollow insides to make it more solid.

Update: I also removed the dish that was holding the hand so you can print it even bigger.

Nope, not Dash Rendar, Ponda Baba, or even the young Lando Calrissian. It's your favorite smuggler Han Solo lovingly packed in carbonite for convenient shipping and storage. Enjoy Han Solo by yourself or with friends. Han makes a lovely conversation piece and will be certain to make you the center of every party.

I owe a special thank you to Sci-Fi 3d { scifi3d.com } and the awesome free STL editing package Netfabb { netfabb.com }

Makerbot-printable pliers for light-duty uses. Designed to be useful for holding small things during inspection, or simply doing things fingers can not.

There is a male arm, a female arm, and a printable nut. The female swivels around the male, and the nut constrains the assembly. The geometry of the threads are based on the connections seen in the toothbrush holder and originally in the screwable jewelry box. ( thingiverse.com/thing:899 , thingiverse.com/thing:413 )

Alternatively, if the design is too optimistic, you can try printing two female arms and use a small screw and nut to hold it together.

All three pieces combined use a total of 1.24 cubic inches of material.

i couldnt find the place i his page, so i had to do this

This is a simple sliding case style tripod mount for the iPhone in response to the first remake challenge. All you need is one 1/4"x20 nut that press-fits into the bottom of the case. Many thanks to Daniel Johansson for providing this excellent iPhone 3G model: sketchup.google.com/3dwarehouse/details?mid=22f5cfad1fd21b26ca3028a0a5ef4401&prevstart=0

A simple device to hang your neckties, because no matter how hard you try we all need to wear one from time to time. Similar products in stores are no longer worth the price when we have the means to print our own!

Designed to fit any standard closet rod. There is 1.2 cubic inches of volume, costing around $0.2x in material

Please let me know if you experience any problems.

Today in an elevator I looked at my hair and then at the key in my hand, when I tried to combine those two it didn't really have any calming effect of my gone wild hair. Everybody carries around keys and coins so one more thing each wouldn't matter in weight, however they would matter in style.

Update: I added a hole to the coin and changed the shape of the coin a little bit.

A laser cut business card that folds into a working caliper.

We at techshopdurham.com/ laser these in batches to place pamphlets in.

no fasteners! well nested! optimistic design!

designed for 1/8" materials- scale it to whatever you want, though.

This is a model of Wall-E that I downloaded from the Google 3D Warehouse, opened in Sketchup, exported as a .stl file, and scaled to fit in a Makerbot using Blender.

Well, I'm not sure what to say about this. Its the head of Walt Disney. You can print it. You can play with it. You can even put it on a robot and have said robot storm through a major metropolitan area and cause havoc. Just don't make it Brooklyn, thx. ;)

Oh yeah, I got the original model from here (cleanup was required for printing): davidoreilly.com/2009/01/walt-disneys-head-on-a-plate

A small desk clamp.

Works but it requires a little more super glue than I would have liked.

It was designed to be a PCB holder (the one Lady Ada uses in her instructions was the inspiration).

ladyada.net/images/usbtinyisp/tools.jpg

The base is too small making it unstable.

However I just finished printing it and it works!

To make it you will also need.

3/8 (5mm will do as well) threaded rod and some square nuts.
Square brass tubing ( 3.9 mm ) and the size that fits just inside that.

Needs some more work:

Bigger base , maybe multipart
Better way to hold the clamps

The tar file contains the blend , photos and all the stl files.

This is a model of the classic pulp SciFi rocket, which takes the hero, the sidekick and the romantic interest, to the stars!

For something that fits in a 12"x12" sheet, this thing will tower nearly 15" tall, overawing any primitive aliens you are likely to meet. Well, the shorter ones anyway.

Heavily inspired by Herge's Tintin comics, which are a must read.
