This is variation of my Medical Veinfinder.

Build this medical veinfinder for a friend. Everytime the doctor has to take blood samples for analysis he has troubles to find appropriate veins.

It works fine and is a rather cheap device and helps to reduce the pain that the procedure normally would cause.

The idea is from instructables.com - for details and parts have a look at:

3D Printed Medical Veinfinder

I adopted the model - e. g. no LED trimming is necessary… As batteries I use 2 pcs. 1.5V AA Batteries in series. - See Instrucables for the proper Resistor for the LED (depending from LED and Voltage). There are  also less LEDs (9 pcs).

Push Button has 12mm diameter. E. g. this ones.
