This is the real deal, no derivatives here. These are the real Printrbot in it's current version. I have a bunch of these printing all day, every day.... it works. It is expandable to larger widths and heights easier than any other reprap out there. Period. Its the most inexpensive bot out there being mass produced. And, its now yours to print, build, improve, change.... whatever you like. I can't wait to see what you do with it. I will post pics of all the various forms it takes, news, etc at printrbot.com

A slightly smaller, sleeker, more portable and more desktop friendly version of Johann's Rostock Delta 3D Printer. Key improvements have been made to the parametric nature of the design files with a laser cut frame generated by the SCAD file to accomodate the desired print bed dimensions. Also there's a new extruder design to go along with that will be published soon.

For more details, build notes, and other information visit the RepRap wiki at: reprap.org/wiki/Rostock_mini

More to come in the next few weeks.

Update 11.11.12: It's printing but there are still some problems with the bowden extruder I designed because of weak-sauce push-fit pneumatic fittings. Am redesigning to use a better tube setup. Once verified in the next couple of weeks I'll be posting more details and the extruder as a separate design.

Update 12.09.12: New Bowden design is complete but hasn't been working as well as it should. Still needs more testing.

Update 12.16.12: Updated v2 files for hotend_v2.stl and the still experimental extruder.stl with OpenSCAD source files in source_v2.zip. These changes get rid of the unreliable pneumatic push-fit fittings and replace with 4mm OD PTFE tubing, McMaster p/n 52335K32, and M4 nuts threaded on each end (one in the hotend and another in the extruder).

The laser cutting template and CAD (STEP) we used to for Romo Gen 2.

Wall mount ping pong (table tenis) ball holder and dispenser that holds six ping pong balls.

Tired of never being able to find your ping pong balls? Use this handy holder. Fill it up and when you grab the bottom ball, the rest slide down.

The stl is setup to hold six standard ping pong balls and mount to the wall with #6 flat head screws. The openscad parameters can easily be adjusted to hold foosballs (table football balls) or metric screws.

A very small and inexpensive robot. 4 axes plus gripper. Build on 9g micro servo.

The robot can be controlled by remote control, Arduino, etc

I see that there are different diameter on the shaft from the servo. If the gear does not fit I'll fix a new one. Just send me the diameters of the shaft.

This is a work in progress of an RC nerf tank I'm working on. It uses some advanced gear designs, printed tracks, mainly printed components overall, will look cool and should be very functional.

This was printed on Tiny, my overly large 3d printer. More info available at ottersoft.ca/

Oh, and the gear is supposed to run backwards to push the treads forwards. That is by design... I think it looks cooler that way.

I've got a video on it running now thanks to Marginally Clever (Dan) at Vancouver Hackspace - youtube.com/watch?v=JJc0kGrgPCs

This is a section of tread for a RC Nerf Tank I'm designing.

ROFI is the fifth prototype from Project Biped. It is a self-contained, bipedal robot that uses accelerometer feedback to balance. It has 12 DOF (degrees of freedom) and can walk around while avoiding obstacles using an ultrasonic range sensor. A small on board Android tablet provides the brains and an Arduino mega board provides the hardware interface. All of the designs, source code, and parts lists are free and open source. Detailed step-by-step animated assembly instructions are provided to allow anyone with a low cost 3D printer and an interest in learning about robotics to build ROFI.


A full overview (with source Blender files) can be found at the Project Biped ROFI website:

Testing a caterpillar track that is printable in one piece :)

UPDATE: Here is a video! youtube.com/watch?v=nigrV9n9658

UPDATE 2: New version 1.2 of the tracks and wheels: more curve to avoid slipping

Balloon Powered Jet Car with snap in Wheels,
I have made this Variation because i wanted my son to play with a safer version of this toy :)

droger's adaptation of andromeda's quadruped is awesome! I was planning on making my own design months ago. Life got in the way for a while, and BOOM, someone saved me a ton of time! A heartfelt thank you for that :)

Small problem though - the original design didn't fit the cheap 9G micro servos that I had on hand.

So I spent a *smaller amount of time* optimizing the design to fit the servos I (and a lot of other people might) have in stock.

I zipped up the OpenSCAD versions of the parts in case you need to tweak them to fit your servos or printer tolerances.

NOTE: what's shown in the picture are some mid-prototype parts. The finals are actually nicer with rounded corners and whatnot. Fancy!

UPDATE UPDATE: I cleaned up the OpenSCAD files in the zip package. I know some of you have servos with slightly different dimensions. The new scads should be parametric so that you can tweak a few dimensions to get parts that will fit your servos!

UPDATE UPDATE UPDATE: the parametrics now support different servo horn dimensions!

UPDATE UPDATE UPDATE UPDATE: I've included a beta version of the design intended for those that have the Tower Pro version of the blue servo, based on communicated measurements. No guarantees: I do not have one of these servos to test the fit. I do have some on order, but it could be a couple weeks before they arrive. The beta STLs are available in the zipped archive named case_qp_tower_stls-beta.zip .

This is a cat drinking pond that takes soda bottles (like coke, pepsi, etc) with a pco028 thread as a reservoir. The water level is kept constant without the need for permanent monitoring on your side.
All corners and edges are nicely rounded so your tippy-toe doesn't hurt itself - also it looks much better.

L**** the cat: "Yay, I can haz water *purr*"

Got inspired by the "pond for small animals", my thing is a complete redesign though.

Tank Platform to move around a Web Based WiFi Camera

Scaled up version of the original, Now with Gear Reduction, greater ground clearance, spring loaded tension on treads and bearings.

All Files.zip contains all the STL files, the SCAD files, The Arduino Tank Code and EasyN Web Code.

(Also added Speed Control to Web page and Arduino Code), Need some help getting the web pages to work correctly with IE. Anyone?

I have added a basic connection diagram and a few pictures of the internal connections of the EasyN Camera.

Update 2013-05-29: Uploaded "STL Files For OpenRC Truggy Rev B.3.zip".

Update 2013-05-18: Uploaded "Servo Holder for BMS-620MG Servo.B.1.stl" that will fit the suggested servo from HobbyKing.

Update 2013-05-18: Uploaded "Front and Rear central driveshafts" and "Central drive shaft Joint and Input gear". These parts are modified to be a little stronger than the earlier version.

Update 2013-05-07: Updated steering uploaded by request (See "Updated Steering.A.2.stl"). It has some minor changes made for reinforcement and there is also support added.

Update 2013-05-01: New STEP of the Main Assembly added "OpenRC_Truggy_Assy_B.3". This has all the latest stuff which is mainly small design changes. Among other things below are som modifications:
More compact shocktowers to lower the profile of the car.
Modded Wishbones
New steering with bearings
Very basic body holders for those who cannot make their own.
And anything else i forgot...
Note, don´t print that wing, it´s for show only!!
I have not added any STL´s this time!


Update 2013-04-07: Added STL files for printing in one single ZIP file (OpenRC Truggy B.2.ZIP). Use this if you want the latest stuff! Also uploaded a STEP file of the complete assembly Rev B.2.

If your looking for compatible CVD driveshafts see info below:

CAD file (STEP) file available here: docs.google.com/file/d/0B7TCLh-I8q6YY2ZueFpQdVZqb0E/edit

Link for sourcing: conrad.com/ce/en/product/231121/

Update 2013-04-06: Latest version (Rev B.1) added. I have uploaded a STEP file, will add STL´s later!

It´s with great pride i give to you my interpretetion of a 3D printable 1:10 Radio controlled truggy car.

At this stage it´s very much experimental and will probably need some modifications and upgrades to be what we all want it to be but i would like to think this can be a good starting point!

The core philosophy of this project is that it is for everyone!
Also it is should be as printable as possible, if you have a 3D printer you can make it! So some additional are parts needed such as driveshafts but those can easily be sourced from many places.

I have tried my very best to keep the design as simple as possible and this is so that it should be as easy as possible to modify!

So, not so fancy but it´s yours to do what you want with. All i ask is that you share with others!

The bottom plate is split in two to fit on my printer. When assembled, the bottom plates, center piece and top decks makes for a quite "sturdy" design! Better than expected actually.
On the other hand, it´s also designed so that you can easily do the bottom in one piece using another material if you want and modify or maybe even skip side guards and top deck.

As time was running out i had to rush the design of the central differential housing and servo saver so if your up to it, i would love to see new designs on those.

I have put alot of time in this and spent many nights drinking coffee and battleling all kinds of problems so i really hope you all like this thing! =)

This was an idea I had when fiddling with the balloon car. I spent the day thinking about how to make it instead of going out to buy new balloons, so I haven't actually tested it with a good balloon, but sticking a straw in the inlet and blowing spins it up pretty fast and makes a cool turbo whistle sound.

UPDATE: I actually bought new balloons! 12" "helium-quality" party balloons. They spin the turbine, but they have larger necks so you have to hold the balloon in place and there is some leakage. I'm working on a version 2 with a larger inlet, as well as a larger diameter output shaft.

UPDATE 2: Version 2 is here, and you can see it work! youtu.be/8Q6svYMZowU
It only runs for about 3 seconds, I'm assuming that's because I opened the inlet up? Maybe because I don't want to pop a balloon this late at night again. Sounds cool, though.

**Uploaded a second version (all STL's are in the zip file at the bottom). It has thinner walls around the pivot and can only use 6mm Diameter x 3mm Thick cylindrical magnets to stay in position. Otherwise it's basically the same as the first version**

While watching The Illusionist for the first time I was really taken by the scene where Ed Norton's character creates and gives the locket to his sweetheart. I quickly decided to design such a locket, but after seeing a variety of nice designs floating around on the web I pretty much gave up on it until having this idea to create a box based on the same concept - one that can change shapes and only opens when in the heart shaped position. I've been calling it the Secret Heart after listening to Feist's cover song.

I tried to keep all the components printable or easily accessible at average local stores, but there are a couple random components in this version - either 2 small magnets or a spring from a clicker Bic pen along with a BB (or any small sphere about .17" in diameter). The magnets are really the best to use because they keep the box in the heart shape and keep the lid halves together when opened, but the spring and BB seem to work decently if you can't find magnets of the right size. If you do use the magnets then the spring and BB only act to keep the box in the rectangular shape, which isn't a big deal since friction seems to do a good job of it. I've uploaded a few different variations of the lid for this design, each with a different hole size for different magnet sizes, so hopefully most people can find a usable magnet. If anyone has a request for a different magnet hole size let me know as it's pretty easy to change the model and make new STL's.

Body for tracked robotics vehicle

From Neon Genesis Evangelion

Pretty much identical to the one here thingiverse.com/thing:35402
except rectangular, with legs and a bent vacuum connection..
I also added more holes and grid lines to allow for more detailed molding

This a set of motor mounts for converting a Proxxon MF70 3-axis micro mill into a CNC mill.

Watch it mill! youtube.com/watch?v=mGAO1evsziE

A controlbox for one of my CNC routers. It contains 3 good drivers, a breakout-board and power supply.

The text "Spindle max 2200W" is not right, since the socket has a 10A fuse and the 400W power supply also will draw it's power from here. So it should say about 1800W instead.

The box is NOT made according to the Machine directive 2006/42/EF.

Designed this after having made a couple of CNC routers with moving gantry. It is also my first design with aluminium profile.

Smaller version of my previously uploaded cheap CNC

One of my homemade CNC machines. This is a relatively cheap version. The linear guides consists of 608zz bearings and plumbing pipe

This turbine done from 3 parts: turbine itself, that was used with some changes from thing thingiverse.com/thing:13188 and case that consists from bottom part with motor holder and top part that covers turbine. Even with small 12V DC Motor it works perfect and powerfull enough.

This is a 3 axis cnc milling machine that can mill circuit boards as well as aluminum or other soft metals. The software that comes with the planet-cnc controller can generate g-code from dxf or gerber files. The jog pendant allows one to mill manually, with digital readouts of the axis positions on the pc interface.

Multi-speed planetary gearbox. Should be able to be scaled to reduce the size.

UPDATED Design Rev 1.1, Mach 30, 2013. Changes:
1. 6.5mm diam x 1.5mm deep bore for mounting of Makerbot's MK7 & MK8 nozzles.
2. Second 2.5mm diam. thermistor hole on opposite side.
3. Tumbling for nice uniform surface finish.

Heater Cartridge, as a heating element of hot end, became affordable alternative to power resistor.

This design solves the problem of mounting heater cartridge on M6 threaded barrels,
works flawlessly with Makergear hot end, can replace Makerbot stepstruder Mk7 heater block and should work with other M6 threaded barrels/hot ends.

This is the Mark II model made by PabloFerroDesign modified for print ability on a 140x140 Huxley.
I have also done lot's of changes here and there and a total redesign of the fingers.

If you like your resistor and diode leads to be bent uniformly and consistently, then this tool is for you. It also provides a useful task for the wee little ones in the house who want to assist you with your electronics projects.
