UPDATE: There were a few small errors on the Top and Bottom. I have realigned the screw holes, changed all nut traps to 6.5mm across. There are three nut traps that are shallower than those that are extruded into a solid this is to retain strength. I suggest you use next M3 x 20mm screw for these three. I have also added counter bore holes to the top so that 16mm screw reaches and it is easier to Velcro electronics on top.

This is a fully 3D printable Tricopter based on the RC Explorer V2.5 by David Windestål. There are 6 Parts that need to be printed and then it can be assembled using 3mm screw and nuts, and some zip ties.

This is a green marker for your golf ball. I have used it and it works perfectly. Sits flush and level with the green ready for your golfing partner to putt. Printed with the MakerBot Replicator V2 using PLA.

Thank you, all of you who've made cube gears and posted pictures. Since tbuser made these lovely pin connectors, thingiverse.com/thing:10288, I figured it was high time to make a fully printable cube gear set. Now you needn't bother buying any more screws: this one snaps together.

UPDATE: For anyone without access to a 3D printer, you can now buy these from caesia on her Etsy store: etsy.com/shop/PlasticFusion

UPDATE: New version uses tbuser's new pin connectors V2: thingiverse.com/thing:10541, is much stronger, and prints right-side-up. This is practice for making a heart-gear version.

This design also incorporates a couple of tricks that others may find useful. The center block has two very narrow slices through it, which cause interior walls to form, which help keep the tops of the holes from sagging during printing. Likewise, a cylinder is cut out of the interior of the gears, which serves two purposes. First, it makes a strong internal support for the pin. Second, it makes for less stringing between parts when you print four gears at once, because Skeinforge makes the head go from the center of one to the center of the other, so that the perimeters wipe off the nozzle.

UPDATE: By popular demand, a new version of the center block has been uploaded (BcenterFlat.stl), which doesn't have any internal slits and is oriented to print on a large face. This one is significantly easier to print, though the top and bottom holes do end up a touch tighter than the rest.

This is a tool used to measure the legal size of a cockle.

This is a key tag surf comb. It works great. It has a concave part (with chamfer) for scraping the rails of the board and a straight edge (with chamfer) for scraping the top. It also has the teeth for creating grip.

This is the robot that is going to save the world, don't listen to this 2012 business, Robo Boto is here! I cannot tell you how he is going to achieve this just yet, more information will be out soon so hang on.
Although Robo Boto looks very simple and doesn't look like he has many functions, he does...

Wheeler is a crazy robot that zips around fast on his one wheel. Wheeler lost his legs when he was 5 as they became too rusty. He uses his new wheel as an advantage to zip around helping others. You can trust wheeler to be there in flash when you need him. He's just a good bloke in general and a well respected robot.

He saves people from buildings that are collapsing

RTR is a cute little guy who likes to be happy.

It was awkward to see when I went to assamble the robot that the arm where about twica as big a the legs and since i am not as good at Computer Aided Design I did not know how to fix it. But I endured and here is a somewhat steel robot.

Hi world! This here is the new generation in computer engineering. The result being a non-movable, armless robot that can fulfill your every need except if it requires fore-limbs.

This robot has fought many wars in the battle of WoW.
He tends to get angry often and turns red at the first sign of trouble.
He is 45 years old and lives with his mother

This robot is known for its extreme helpful attitude!
This robot on one faithful day, gave its own legs to allow another robot to survive.
It is now known as Stumpy the robot, though someones it gets teased for not having legs, it still is proud for what it did that one selfless day.

Bob is a robot that will become your best friend in life. Bob is aimed for ages 0-2 year old's and has no tiny parts.

My robot is for the MakerBot Robot mascot contest. Nuff said.

My Superman Junior Bot is a superhero who can save the world, if your near or far superman will be there in any circumstances. From jumping to climbing even flying he will assist you hopefully no guarantees. He is quick as flash but he is vulnerable to apple pies :)

This is my Makerbot Mascot that I made for a school project (year 10) I think the overall design is good, apart from it may not be printable.

This is the fastest robot in the world, it gave up it arms to increase it's leg power and therefore makes it faster. it's ears aerent only there for fashion but it is there for super speed. it unleashes fire out of it and makes it faster.

This is robot Junior. He was created to help people with what ever. He can do anything that you ask. He never refuses to help anyone.

MakerBot Robot Competition

This is Frank, he is a MakerBot Robot V1.7_13. Frank is a robot designed to bridge the language gap between Humans and any possible Extraterrestrial life that tries to communicate with us.

Since Frank toddled off the production line late 2011, he has been pondering a question while waiting to fulfill his purpose. The question he has been pondering is whether or not he should ponder the meaning of life or whether he should ponder how to level up his Caterpie in Pokemon. This question shall plague him for a while yet as Frank was build to Ponder and discover.

Pizzicato Jr. was a robot that went down in history for being the last surviving robot of the invasion of ants. The ants used surprise to their advantage to come to earth, without any preparation. He single handily took on the army whilst the other robots gave in.

a robot i made for school assignment

This is a basic 2x2 lego brick - slightly warped.

Designed from scratch - very similar to this:
thingiverse.com/thing:591

I was looking for a Duplo helicopter for my nephew for Christmas but couldn't find one with just a helicopter so I made one. He's 3 so I wanted to keep it simple and only put 2x2 Duplo sized studs in the cockpit for a Duplo figure and made the rest kind of fisher-pricey. Works well with all the Duplo bricks I have tried with it so far. I was having some printing issues with larger objects so I also tried it at 1/2 scale which makes the studs regular lego size. I guess the printer isn't up to the tighter tolerances needed for lego because at this scale the lego parts are a bit hard to get on though they do work.

I think of my self as an artist and not an engineer so the tolerances are less than great and it may have some pretty big design and structural issues. My 1:1 Duplo print mostly clicked together and holds without glue but I had to clean and sand some of the parts a little bit more than I would have liked to make it work. Had to really sand the holes for the rotors so they would spin freely. I printed these on my UP! with the normal and .25 mm settings. Maybe with fine and .20mm settings it would work a bit better?
