Water bladder dryer

prusaprinters

I was frustrated how long it takes to dry a water bag (water bladder) after using it. Also, it was worrying how moisture stayed within the tube. I decided to give it a try and designed a dryer that would hasten the proccess and force the moisture out of the tube. I am aware that it doesn’t look slick or smart - the idea and the design is pretty primitive to be honest. However, it works really well - the bladder and the tube are dried safely within an hour. It is designed for a Decathlon water bladder but I am sure it will work for other brands too (Platypus, Camelbag, ..).The dryer utilizes a standard 120mm axial ventilator (fan). It basically consists of these parts: the fan itself, air outlet, legs and “shoes” for the legs (these are optional). You can easily print all parts except the shoes with PLA or any other solid material, it really doesn’t matter. The shoes are not-essential and if you decide to do them, print them with TPU (or similar soft material). Also, it really doesn’t matter what infill you choose. I would suggest the following: Outlet – around 15%, Legs – around 40%, shoes – around 50%.I haven’t designed any air inlet or protective grid for the fan since it works fine as it is and I don’t worry about safety. If you want the inlet or grid look somewhere on the web there are many already done designs that you can use.If you need more information let me know, I will try to help.
