Remixed the gear to work with a shorter blind cord (i was unable to get anything close to the original). Also widened the stepper hole more (original didnt really fit) and added a side M3 screw hole.

Same as https://www.thingiverse.com/thing:2746443 but i removed the screw holes to use 3M backing tape instead

Interesting fact, tampons are almost the same size as a AA battery. Not a user of them myself i was tasked with creating a case to hold 2 of the aforementioned. The premise being that they needed to fit into a purse/bag where a larger box would not venture easily, and individually they would be prone to damage. 

So a repurposed AA battery holder is perfect size for a slim line, easy to carry tampon case.

What better way to get your ironically delicious revenge on trapping a mouse than with a weighted door with none other than Mickey mouse himself on the back of the door.

This version doesnt need anything else added and will print heavily enough to open but not be opened from the other side, what better way to mock the mice inside your mice proof container. 

*Update, made the hinge hole a little bit bigger to fit a stretched out paperclip

#Mastermind style safe unlock box
This project turns a ikea perspex display box into a lockable and unlockable display case using a Arduino MKR NB1500 board for connectivity. The idea behind the safe is to open/unlock when a user gets the right code via SMS as part of a mastermind style game. 

Connectivity in this build happens via the NB1500 which is catm1/narrowband enabled but a wifi board could just as easily be used. 

Both the server side code and the arduino sketch run via a MQTT broker (Mosquitto)

##Parts
- Ikea BJÖRNARP https://www.ikea.com/au/en/catalog/products/70364351/ 
- Full sized servo, (i used a AR-3606HB) 
- LED strip (optional), just adds a nice effect and helps highlight the case.
- Mobile battery (i used a 10000mah dual usb power pack, ideally it needs to have 2 usb ports and support 5v out). 
- USB cables, these are used to power the LED's and the Arduino on 2 seperate power lines (so long as theres 2 usb ports available). 
- Spare wires (to solder the LEDs).
- Epoxy (to glue all the bits into the box

##Instructions 
Print out all the parts including 2x of each LED strip, this project can be built without using the LEDs but it does add a nice effect to the box and can be used to highlight when someone wins. 

All the prints i printed at 20% infill and 0.25 height with supports on the things that need it.

Solder strips of LEDs together making sure of the direction of the LEDs and that you cover the LED strip prints from above. Splice an old USB end to the end of the LED strip (power only!), you'll only need power and negative lines from the USB as the data line needs to run to the arduino (it controls the lights). 

Glue the LEDs to the LED prints using small amounts of epoxy (usually the sticky backing on the strips isnt enough to hold them). Once the LED strips and LEDs dry glue into the top edges inside the box making sure the USB end fits into one of the back corners (to keep it out of the way). 

The rack and pinion style gearing can be a bit tricky to lineup, basically the rack print from above needs to stick to the door and the servo with gear needs to mesh into it. In my build i cut a small hole at the side of the box so that the rack can slide the door open with the rack running through the hole at the side. 

Screw the servo into the servo print above, in this build i used a AR-3606HB from Core Electronics (https://core-electronics.com.au/power-hd-continuous-rotation-servo-ar-3606hb.html). I also used the rubber stoppers from the servo to try and reduce vibration (and noise). 

Once the hole is cut in the side of the box and servo screwed in and ready to go, carefully glue the rack onto the door so it slides through the side. Once dry glue the servo to the bottom front of the box so that the gear will mesh into the rack glued onto the sliding door. 

Plug the LEDs data line into the pin you want to control the LED strips from, Plug the servo into the iot board you used. The servo i used in this build needs 5v so is powered from the 5v pin on the NB1500 with a data line running to a pin on the board. 

For those using a Arduino MKR NB1500 i've also designed a case for it, see https://www.thingiverse.com/thing:3460266

When everything is glued, dried and assembled load the server side code and the sketch to the arduino or IOT device you used. Plug the USB for the LEDs into the battery and power the arduino. For the arduino i just powered this build from the same battery the LEDs run from and the servo running its power from the Arduino. This can be changed around depending on your build requirements. 

I wont go into the code side of things but the full code for server side and device side can be found here https://github.com/telstra/AWS-Summit-2019-Demo-Game. The game itself (written in Python) puts a message into a broker queue that the device then receives and triggers the door to open.

## Mini trophy print 

Made for the [IBM Call for Code](https://developer.ibm.com/callforcode) 2020 hackathon in Australia & New Zealand, This mini trophy is the perfect way to recognise the winners of your next event. 

Ive included the blank top so you can customise with your event logo and ive included the IBM rebus version i created for our events as an example. To create your own take the blank top into your favourite 3d editor and add your logo/text or content of your choice. 

In the example pic i printed the top with a dual extruder so mixed two colours in. 

The base has a tab wedge cut into it allowing for ergonomic placement of the top allowing for easier ways to apply a small amount of glue enabling a seamless and hidden finish.

This is a remix of the Kitchen spool/Paper Towel holder designed to fit a ikea Forhoja (70177024) - Kitchen Trolley http://www.ikea.com/au/en/catalog/products/70177024/ 

This is the print for the left side so will need to be mirrored for the right side. 

There is still a minor amount of play once attached to the bench so i secured it with a small piece of cardboard.

Keyring designed from the 2014 Battlehack (https://en.wikipedia.org/wiki/BattleHack) logo designed using gravity sketch in VR. 

Originally i was going to put a loop in for the keyring attachment but ended up cutting up the axe so it can be looped into the top of it.

iPhone 7/8 plus back of seat holder for planes, saves needing to have the tray table down and means you dont have to hold the phone. 

With a slim fitting case it will be a snug fit

TODO: future version could possibly support clamp resizing

#A Door Prize Trophy

Created out of a conversation for a community run event that started as a joke and ended up escalating quickly. 

Crafted with high grade 3d rendering it is the engineering culmination of the union between a door and a trophy base. With the added bonus of a plaque interface allowing for the application of an event logo, via some slight customisations, or via careful positioning of a sticker or sharpie. 

This is the perfect trophy to give someone for either winning a door prize at an event, Winner of the year at a Door convention or for introductions a networking event - opening doors (you decide). 

#####Made using the following prints
- Door (scaled down) - https://www.thingiverse.com/thing:365452
- Trophy Base - https://www.thingiverse.com/thing:520101

(Note: I took the pic before i edited the STL to move the door into the base more)

Printed on a Prusa clone with 10% infill at 0.15 layer height.

Couldnt get the bearings needed for the MTvplot project so i just made my own, two halves glue together (carefully!) using standard superglue, extra care is needed in doing so as you do not want to glue the tube to the gondola arms. 

Pen holder then just glues on the outer tube using superglue as well
