Rather than spend time printing springs for a project, I made this little mold to make them out of raw 3mm PLA filament. It measures 3/4" by 3" tall. Since there are no shear planes in this twisted filament, the springs it creates will be a lot tougher than anything printed.

I think this concept could be used to produce torsion springs as well as conical compression springs with different molds.

If you wrapped the filament around a dowel with the sides of the filament touching, you could make an extension spring instead of a compression spring.

This is the landing gear i designed for the mini quad frame that was desgined by tosjduenfs. It is meant to have the motor base pressed into the arm and down into the landing gear to help hold it on. You could aslo print a plug that would go into the holes if you mounted the motor on top. i just hot glued the landing gear on to test how it would hold up and so far it has not fallen off.

We modified design of our previous publish: hydropw1 - thingiverse.com/thing:34813
We reduce stainless steel use and increase nylon 3D printing parts.

We hope you to improve our design.
Thanks!

For a rotary encoder (i bought this one: pieterfloris.nl/shop/product.php?id_product=572) i've made a holder that keeps it into place, makes sure the rotary encoder itself can not move and still enables the wheel to rotary easily.
The wheel is also custom made, and fits perfectly on the rotating part of the encoder, since it's got a flat side to it. The piece of rubber i rapped around the wheel comes from a very cheap mouse from a brand called sweex

An easy-ish conversion for the manfrotto 3 way head to streamline taking of spherical panoramas. Made 2 so far but still work in progress.

About 170 degrees vertical fov with samyang 8mm (corner to corner)

See it in action: youtu.be/m-kqBCw5f4w

Key Parts:
Nema 17 motor
Arduino nano
H bridge
Connectors
2 printed gears
1 printed quick release lens clamp
1 printed motor support
cable ties :D

This hack is completely reversible, ie you can take everything off and have your panoramic head in its original condition again. The parts are attached with cable ties and hot glue which comes off with a bit of force.

More info to follow if anyone is interested

This project is a continuation of my iphone panoramic head project (I didn't have a 3d printer then) iphone360.ilyatitov.com/

Want more power?
Your in a storm... All manner of power gone.. You need to make a call.. you turn to your minty boost....

Where is it? well now its bright freeken neon green so it's not like you will misplace it..

You pick it up....
Old minty. $%@#$%@#$ the batterys are dead in this also...

Super Minty: I love you minty you saved me once again....

I hope you enjoyed my story ;)

Disclaimer: Minty has always got hot in the past.. The manner of how hot will not change but make sure your wires do not touch the chip.. use common sense when tucking the wires into this case.


Making the PLA spike for the hindge

This is a standalone Raspberry Pi case with integrated power supply and display. As well as the printable parts there is some circuitry and software involved.

I made these for drilling out holes in 3D printed parts.

This is a project that we are working on at Idaho State University in the Robotics and Communications program. We first designed it in Autocad and are now working the the programming. For more info on the project or coming to school and learnig about building robots please visit sites.google.com/a/isu.edu/rcet-projects/

Completely customizable collar stays!!
No more using and losing flimsy generic stays.

Monogram with your initials, name, or image/logo.
Show off your tech/geek cred while remaining stylish!

I initially set out to learn Openscad and recreate my collar stays originally designed in Tinkercad (now defunct). Soon I realized how easy it was to use Openscad and it all spiraled out of control.

Pretty much every part of this design is customizable. You can add relief or embossed text or images. Adjust the sizing to get the perfect fit for your shirts.

Seriously, get rid of your old collar stays and start using your own personalized ones.

They can also be adjusted to become tags, bookmarks, herb/plant markers, and more.

This is an aid to make it easier to calibrate the x & y axes of your 3D printer.

Using calipers to calibrate the x & y axes was a big chore for me since I could never seem to get consistent reference points on the carriage & frame to make measurements. I was resorting to taking several measurements (invariably all would turn out slightly different), and then average the results.

This thing is just a simple pointer that you can clip to the carriage. The pdf file is a mm graph that you lay on the bed.

I needed some constant lighting to watch my printer,

especially with the new roll of filament I just bought,
a slightly translucent lite blue,

which is truly invisible on blue tape !!!!

So using this ring light:

I designed a mount that attaches to my extruder.

This is a 3d printable case for a Nixie clock using IN-14 tubes

You'll have seen a few of these captive sphere models here on Thingiverse, so there's nothing especially new about this one.

Except that it's the result of a tutorial explaining how to get started with OpenSCAD, as published on my blog 3D Genius:

3dgeni.us/getting-started-with-openscad/

The tutorial starts from scratch and explains the basics of working with this most useful of design programs. The whole thing is described in just 10 lines of code, so if you ever wondered what OpenSCAD was all about, now's your chance to find out.

Small low power 3 phase A.C. / D.C. generator designed for low energy applications using wind or water power. The generator is stackable allowing you to build up a working system of multiple modules to provide the voltage or current required. Connecting a module in parrallel boosts the current and connecting in series boosts the voltage.

This is version 2 of the GoPro HERO3 mount to suit 450PRO helicopters. Ensures a slight downward angle of the lens in hover. Allows for use of velcro to secure camera. Now allows user to glue camera part to mount part on an angle to ensure camera is level during hover.

These are landing legs for thingiverse.com/thing:89140

The camera mount should be able to mount most cameras up to 100mm wide. If you don't have the screw required to attach the camera to the mount, velcro would be an option as well.

Protect your Pi with a really nice customized case. Based on the Adafruit's case style.

* __2013-05-16__: Small update (rotation and base borders are smoother)
* __2013-05-14__: First version

This thing is designed to make small torsion springs with music wire of about 1mm in diameter. Similar commercial spring winders can be prohibitively expensive if you just need to make a few springs. With this design, you just need a piece of steel rod for a mandrel, some music wire, and you're set.

Updated 5/16/13: improved geometry

Directions:

* Drill/ream out the holes in the base and the handle

* Insert a mandrel

* Clamp it down

* Wind some springs

* ???

* Profit!

Print your own desktop manufacturing kit to produce precision rubber parts directly onto the iPhone 4/4S or iPhone 5 with sugru.

There are 2 sets of molds here: 1 set for the iPhone 4/4S and another set for the iPhone 5. Each set has 3 components (make sure you print them all)

You will also need a set of nuts and bolts:
Metric: 8 x M5 x 25mm bolts + washers and wing nuts.
Imperial: 8 x 10/32 x 1" bolts + washers and wing nuts.


UPDATE - 17th May - We've just uploaded a new set of molds with an improved draft angle for better release. Please download, edit and create the molds as you wish.

If you think you can push this technique further, we're giving free sugru to the very best ideas.

What would you like to try?

I liked both Emmett's gear bearing and tjhowe's parametric airless tire. The next step was to put the bearing in the tire!

The stl uploaded is the original diameter gear bearing with 20mm of airless tire around it. I have shrunk the thickness to 12mm and beefed up the spokes of the tire to 0.8mm so should print as two filament thicknesses.

The OpenSCAD file is just both files from the orignal creators in the same document with a couple of minor edits make it hang together.

This is a Moon Phase Clock.

Being broke 2 days before Mother's Day, I knew I needed something for the wife, but didn't have any cash.

Scrolling through thingiverse, I though a maybe some glowing lithopane thing would be nice, when I stumbled upon benjaminedwardmorgan's Moon Lithopane...

And it hit me. My wiccan wife often would miss the full moon - lucky for me, I am not a frog yet - and since I make all kinds of LED clocks, I decided to make for her, a Lunar Phase Clock.

This is that clock.

This is a spin-off of MikeyB's excellent 3D Printed Quadcopter. I have made a number of upgrades and modifications.

The arms are now solid. I ran several tests and the solid arms only weigh around 1.5 grams heavier when printed at 25% infill and are more rigid.

I beefed up the landing gears after having a few of mine break, and rotated the motor mounts by 45 degrees so that the wiring is neater. The ESCs mount on the bottom and are enclosed by the ESC covers.

The wiring is contained by the snap-in sidewall covers.

The top cover protects your electronics, and has a removable window for those of us with KK2 boards to facilitate tweaking the settings without having to disassemble the quad.

I also modified the top plate to accept an FC mounted in either X or + orientation.

I will update this thing as I continue to mod and update my quad.

As of right now, this is 100% tested and working in PLA. I printed the ESC covers and other cosmetic parts in ABS.

EconoBot with a Dagu servo powered scanning head and Soccer/Sumo Shield. Robot has 4 Robodyssey IR prox sensors and a Robodyssey RAMB III motherboard with a Arduino compatible Teensy 2.0.

A prop bumper cage and 'Quick Swap' battery holder. This protects your Crazyflie from buzzying the props against the ceiling and things. It also provides an easy quick swap battery feature and an added bonus - You can easily carry or grab your Crazyflie by the cage too. ;-)

Total weight of assembly is ~4.5 grams.

Alert: At this time, this is a feature add-on to the Bitcraze Crazyflie frame version 1.6.5 and earlier: thingiverse.com/thing:84169

If you mount your battery underneath then simply remove the battery holder feature. Or leave it?

-- Added bare frame stl for the weight conscious. It is a remake of VGER's.

This is a work in progress.

I need to balance props for a quad and I'm hoping this will do the trick.

I plan on drilling out the hole and taping for a long thin bolt so the cones can be adjusted to the prop.

Then balance the bolt on a simple wood frame. Because the surface may not be perfectly level it will be important to flip it back and forth during balancing.

5.15.13 I have reduced the height of the cone. The tips of the cones would touch unless the smallest prop adapter was fitted.

here is a little button I designed after an existing one. It was an european Bosh oven.

See github.com/uplake/BezierScad

Updated 5/10/13--fixed triangle winding in centered BezWall; use polyhedron for variable-height BezArc.

I wanted a bezier library that could handle an arbitrary number of control points. When working on thingiverse.com/thing:77586, I also wanted to rotate extrude a "wall" defined by a bezier path and a width.

BezWall is the workhorse function. The "ctlPts" parameter accepts between 1-8 bezier control points.

The parameters "width" and "height" accept static values (e.g., 5) specifying the width and height of the wall. If height is 0, it will generate a 2d object you can extrude yourself.

The alternate parameters "widthCtls" and "heightCtls" accept an array of values that will be bezier-interpolated along the length of the wall.

If the "centered" parameter is "true", the wall is centered on the path defined by "ctlPts". Otherwise, one edge of the wall is defined by "ctlPts".

At the moment, there is no documentation! But there is a test file that runs through most of the available features.
