Bottle rocket (+launch platform)

What?

A bottle rocket launch platform with gardena connection for quick and safe release of the bottle.

Pressure is added to a bottle with some water by a bicycle pump. when the bottle is released from the platform, the pressure expels the water in the bottle, generating lift.

Why?

Same as usual… got bored.

How?

Requirements are:

* A bottle (coke bottle preferred as they are sturdy).
* A bottle cap that connects to the gardena connector (I 3D printed this one)
* A Gardena connector, connected to a bicycle pump (I made a small platform with the connector, a one-way valve, and some longer hose to connect to the pump).
* A bicycle pump (or other pump capable of delivering around 2-7 BAR).

You fill the bottle with some water, connect it to the hose, and pump in as much air as possible (be careful not to pop the bottle).

Then release the bottle and watch it fly.

Minion Bristlebots

What?

My own take on the classic bristlebot, with a 3D printed battery holder.

These little buggers move around thanks to the vibrations from the motor.

Why?

To give a workshop.

How?

The vibrations from the motor make the bot move around, by bending the hairs of the toothbrush backwards, the bot moves forward (kind of :D).

Requirements are:

1 toothbrush
1 vibration motor
1 CR2032 battery
1 3D printed battery holder (found here)
hotglue
(googly eyes)

Instructions on how to put them together:

step 1: cut the head of a toothbrush
step 2: print the battery holder
step 3: attach the vibration motor to the battery holder and put the 2 leads into the holder block so the battery can touch it.
step 4: hotglue the holder to the toothbrush head
step 5: cut (if needed) the toothbrush hairs to length and bend them backwards so the bristlebot will go forward instead of in circles.
step 6: decorate and race!

 

Current status:

Finished, thinking about making a racetrack for them.

3D printed chess set

The 3D printed chess set: custom design, complete with printed board.

What is it?

a free to download design of a chess set that you can 3D print, complete with all parts, including the board.

Why?

When I got my 3D printer I wanted to create something that could stand on my table, and be a conversation starter. I designed the chessboard and started printing. It works really well as a decorative piece.

How?

The design was made using tinkercad, and it was printed on a PP3DP UP! mini printer. The files can be downloaded from thingiverse but be warned: the complete set takes around 45 hours of printing on a good quality, and you will need at least 2 colors of filament, 3 if you want the border to be in a different colour.
