Weighing spoon / spatula
Description
This design is a weighing spoon used to handle small quantities of powder. I designed it to handle Gold(III) chloride witch has the bothersome property of instantly corroding any metal i tried, and stick to anything it touch if there is any humidity in the air... So i designed an "automatic" handle that allows you to get rid of the tip without contact. This handle uses a spring with an outer diameter 6 to 7mm, wire diameter 0.5 to 0.7 and length 30 to 50 (I used 6*0.5*40). you also need a 12mm (head included) M2 screw. Alternatively you can use the "handle simple", simple to build, but that requires you to change the tip manually. I provide 6 types of tips of various sizes and shape depending on your preferences.
