Shark Comb

Combs are highly underrated, if you are going to use one why not go for this little beauty? There are numerous 3D printed models you can go for; however, I would definitely give an advantage to shark comb. 

You can download the template online, from YouMagine and it takes around an hour to print. If you don't like the finished product, you can start experimenting with different objects yourself!

Earbud Case

With the best will in the world, we all end up just ramming headphones into our pocket. As everyone knows once out of sight quantum physics dictates that the wires defy the laws of logic to become preposterously entangled. Take control of your world by printing these nifty earbud cases from Thingiverse. You no longer have to search for open ends or untie knots as this model allows you to roll the wires around the case. 

They take around 30 minutes to print.

AA to C Battery Adapter

Need a C battery but only have a bunch of AA's lying around? Hey no problem, the only real difference between the two is the size. They offer the same voltage and C's are actually more expensive. Try out this 3D print hack for "converting" the AA to fit any gadgets that need C batteries.
