For those of you who are not familiar with this device checkout http://bobbeck.com/ Unaccepted by regular medical sciences but has cured so may people. This casing is for one of the devices of the Bob Beck protocol, the blood purifier. For good results please use the whole protocol and not only this device. The electronics involved are expanded with a little voltage trippler which makes it possible to use one 9 volt battery. This design has the cheapest method for adding cotton to the electrodes by using simple cotton buds. You can slide the electrodes for the right position to the blood vessels at your wrists. This casing is open source, make it better at https://www.tinkercad.com/things/jBFEB7weoKd-bob-beck-blood-purifier-complete-casing Layer height for 3D printing is 0.2mm. You may use ABS or PLA it makes not really much difference for these objects. It is important to make the cotton buds wet with water which has salt in it. This is necessary to make the conductance the best for the pulsing trough your skin to the blood vessels otherwise it seems like the pulsing does not work at all. Start the first day with 8 minutes and every next day 8 minutes longer until you reach 2 hours a day for 2 months.
