Medical prototype. My kid was in a hospital recently, and they had to put him on an IV. The current practice here is to place a support _Under_ the wrist, tape everything up (for immobilization), and have the IV on top of the wrist. The problems we encountered were:

1. No protection for the top of the wrist where the IV was, causing much anxiety on my part on whether the dude was gonna knock his wrist against anything and dislodge the IV needle, etc (wince!)
2. Total lost of dexterity in the hands due to the support block

This prototype proposes to accomplish the following:

1. immobilization of the wrist from the top instead, secured by velcro bands (currently testing using velcro cable ties)
2. top of the wrist is protected by the Y arms of the brace, while still allowing the palm area to be secured by yet another velcro band
3. Fingers can still move (a lot more than before), without compromising the IV placement
4. A lot faster to deploy (dude had to change his dressings 3 times in five days, and each time I freaked out more than he did :-P )

Yet another overwhelming silly weapon-wannabe. These banana nunchucks let you bring your favorite carb/proteins to the gym while flexing biceps at your fellow Kickboxercisers.

Please note that these Banana Nunchucks work better with straighter* bananas.

A coke and mentos driven engine.

Inspired by their recent rocket car, but exploring alternative designs to increase efficiency and reduce wastage of my fav soft drink*

See the rocket car here: eepybird.com/featured-video/the-coke-zero-mentos-rocket-car-2d/

The EepyEngine is driven by the usual 0.5 inch PVC/Coke/Mentos setup, and hopes to be a lot more efficient than driving acrylic rods. You can also mount many of them together through a long M6 threaded rod to increase torque.

*technically, i love the non-diet, original recipe Coke; not the recommended diet variety.

In case my better half thinks that the cupcake/3D design is only for fun/evil, as well as an inherent desire to change the world, here is a design suggestion I submitted to BP for evaluation in sealing the fractured pipe.

I know that some/many of the most creative minds in the world are on Thingiverse, and I am hoping/urging the other operators to spend some time looking at how to seal the pipe and save a lot of carbon-based lifeforms.

BP is taking recommendations at: horizonedocs.com/artform.php

Not entirely satisfied yet with the mean-ness of my katana, I decided to go to town with a revolver too. Here is an iPhone case you can tuck into your board shorts (front or back is fine) and answer calls with a really nasty look on your face (remember to keep your other hand on the katana umbrella).

I love the stuff from ThinkGeek, but ordering from my part of the world is not possible without 3rd party purchasing/shipping.

Case in point: the beautiful Katana (Samurai sword) umbrella - thinkgeek.com/geektoys/japanfan/b625/
(I really tried. I cannot find my country in the drop-down list, and even pleading via email was in vain)

So! Here is a cupcake printable Katana handle for Deliverator-wanna-bes.

This is a derivative of the super awesome Printruder II by Zaggo

thingiverse.com/thing:1980

1. Incorporates a prototype design by Zaggo which allows direct access to pinch wheel - Easy flossing and access to the grub screws.
2. Idler bolt is loaded at the M4 end, and then pushed towards the pinch wheel - this allows the following deltas:
- No need to dismount the motor if you want to extract the idler block
- Additional space gained allows now a 'guide' ramp for the post-pinch-wheel filament to be guided towards the heater element
- Idler block is now more secure, as it is nowhere near the insertion channel when under load

The existing 626 bearing based idler may not fit the timing belt pulley on the Printruder. This is a redesign based on the narrower 688 ball bearing (4mm depth) that will fit the pulley.

Thanks to Zaggo for the awesome Printruder II

Drop-In Y-stage for Batch 9 Cupcakes.

1. Printable in 1 sheet (only 6 pieces)
2. Uses minimal hardware (see instructions)
3. Solves issues of:
- bolts jammed against guide rods
- Y timing belt against Y-stage
- leveling around Y-axis

I am actually just Borg-rifying my cupcake one part at a time :-)

The Helping M is a very portable clamp to help you hold in components during soldering jobs.

I started on this _after_ hand-soldering the 52 SMT components for the HBP :-P

1. There is no need to bend the component wires to hold in the component during soldering
2. Adapts to different sizes of circuit boards: Max about 7 to 8 inches wide
3. With some velco, interchangeable heads allow usage for capacitors, resistors, ICs
4. Once mounted, The Helping M is able to move laterally to press on different components
5. The Helping M slides up and down your board easily too
6. The Helping M also serves as a prop when you flip the circuit board around, to position the board in the right position to solder easily

Variation of (with much thanks to):
1. Wobble Arrester by twotimes: thingiverse.com/thing:2151
2. Z-axis floating-nut-arrester by Bophoto: thingiverse.com/thing:3052

I didn't have a 7mm pin, but I have plenty of 1mm brass rods; hence this simple variation

This folding guitar stand is actually attached to your guitar. Folded up, it does not impede with your guitar playing, but once you need to put your guitar down, just pull out the support legs and you can safely place your guitar on the ground. Great between gigs!

Simple box/adapter for a 15 x 15 x 15 cube of sponge to clean the filament before it enters the extruder. Helps to also keep bugs out (yes, i do get bugs flying into my bot, into my extruder and smearing their insides all over the insides of the Mk4)

This is a highly portable monopod with a 360 degree swivel (well, in one plane at least :-) ball joint. It is to be mounted on top of drink bottles (will fit most PET bottle tops).

Easily carried around, this allows you to quickly set up self-portraits or even closeup of desktop items using one of the most common items around, an ordinary soft drink bottle.

Tested only on small point and shooters, and a Flip camera - i have no idea how the joints will work with SLRs :-) - in any case USE AT OWN RISK!

This design is Not Entirely Original - I first saw a camera adapter for a drink cap last week, and decided to integrate that with a ball joint found on Thingiverse - Thanks Erik and MakerBlock!

I travel a lot, and I watch a lot of movies on my iPhone. This stand lets me prop up the iPhone in landscape/portrait mode, and allows adjusting of the iPhone lean angle, especially on the airline seat tray. Once the stand is unfolded into 90 degrees, I can also pull up a couple of magazines from the airline seat pocket, hook the stand onto the magazines using one of 2 available sets of slots (you decide which angle is best for you) and place your iPhone for your own optimal angle.

Updated:
This is the fourth iteration so far, and a great new feature: resized to fit iPad as well! - Airline mode works only for iPhone/iPod touch.

A generic Ikea™ toothbrush holder was designed for really large animals like rhinos and bears. Holder is simply sized to sit in existing slot, and hold an electric toothbrush head.

Prototyping an adjustable nut-cam combo for rock climbing protection. Nuts are great, but not adjustable. Cams are fast to use, but costly due to design and manufacturing complexities. Hopefully this design can help bridge the gap, melding a nut-like approach with cam-like adaptability.

Update:
1. Broken up some parts for easier printing
2. Glue in the slots. I had to sandpaper everything to fit properly
3. Use M3 nuts to secure
