A normal 3d scanner costs around 350 dollars with my way 'you' yes you! can create it under 100 dollars! What you will need is a very basic knowledge of MCU.
It has MILLIONS! of use cases, you can use it in music industries, you can use it in bio-medical fields..... 3d printing, academically etc. lets see how!
It is very difficult for startup music industries to make music boxes again and again because of its expensiveness well by this 3d scanner you will only do this once! you can change it afterwards if you want by software like blender.
Everyone have different joint sizes but joint sizes available are generalised which makes it uncomfortable to work well we have a solution for that too! you just need to scan the joint and 3d print it!!!!
Often biology teachers make a lot of diagrams to make students understand different bone structures but now... you just need a 3D scanner! Scan it, label parts, and send it to students!
Suppose you want to make a copy of an object , scan it print it!
Well I can a lot more usages but I think this much can tell its elasticity. Sometimes we just need to know what we need!
