I am a sophomore in Monta Vista High School in California.

An ordinary brush holder often collects old water and eventually becomes more gross than the dishes you need to clean. Additionally the counter underneath the brushes become gross. Unlike others, this brush holder attaches to the base of the faucet for easy access and avoids the disgusting mess that appears on your counter. In addition to this, if water gets collected in the holder itself, it gets drained using the elephants trunk.

Supplies

fusion 360
3D printer

Step 1: Create the Bottom Body

Using fusion 360, create a semi circle body big enough to hold brushes so that the back lays flat when attached to the sink.
In the front of the holder create a pipe for the trunk that cuts into the body making sure it is completely hollow
Create two knuckles facing inwards for the hinge. Place them about the length of one knuckle apart.
Make two eyes and ears

Step 2: Create the Top Body

In fusion 360 create a hook shape so that it fits around the base of your sink
Add a knuckle for the hinge on the bottom portion, facing down

Step 3: Finish Hinge

In fusion 360 create a cylinder
- diameter should be smaller than the holes in the knuckles
- the length should be longer than the 3 knuckles combined
