Icebox extension

thingiverse

Plenty of nice cool beer waits patiently in the icebox. As soon as you decide to take it out, though, the magic spell is broken, and the warmth begins to seep back in. So why not think outside the (ice) box? The idea for an icebox extension was born. A 3D printed icebox extension is exactly what we need - one that actively cools a bottle, tin or glass of beer right there on the outside of the box. At its core, this nifty gadget employs a Peltier element measuring just 4x4 cm in size. It's no secret that this low-cost heat pump comes at a reasonable price and gets the job done efficiently. It works by transporting heat from one side to the other - instant gratification guaranteed. All it takes is some electric current flowing through that magical Peltier element, and watch as one side heats up while the other side cools down seamlessly. Peltier elements and their respective heat sinks can be easily sourced in hobby electronics shops. However, remember that when choosing a large enough heatsink at the hot side of things - all will be well, but only if that fan you're using is more than powerful. No extra gadgets needed then.http://www.aliexpress.com/snapshot/6324491655.html\nIt won't break the bank either as supplies complete units with fans and heat sinks are yours to purchase for a mere $18. A tiny tweak may be required to make these printed parts fit perfectly within your setup (check out this photo of a white box). This marvelously versatile gadget comes in three distinct flavors - one that is particularly special. It has two layers working together in perfect harmony as a thermal insulator. One side proudly houses the Peltier element with its very important pair of heat sinks, while the other patiently waits for the coolness to set in at the bottom via the powerful fan.
