Since I am going to be working with aluminum and other materials, I bought a 10-piece file set for U$S 9.98. However, I still need to buy more tools if I wish to work faster, else, I will have to go slowly and keep improvising.
Building a 3D printer using other printers, picked up from the street, is like building a puzzle using different puzzles sets. I must confess that it would be easier to build a 3d printer from scratch but I don’t have the resources to buy a lot of materials and tools needed. Also, this is more challenging, original, and I can learn more than building a 3d printer from scratch.
