Reppy is a self-replicating 3D printer entirely made in Blender by 16 year old student. It took me about a year to complete the design but still, it isn't perfect. It has all started in November 2018. I did sketch some drawings how would the printer look like. Then I moved to my computer. I decided to use Blender. The process of making and modelling wasn't without complications. It took me a year to move through the biggest problems with Blender, my Chinese 3D printer and slicer. Now I can share my biggest project in my life with You :-). You can modify the parts and make the project better.
IMPORTANT: You have to scale all STL files to 5000 %
Have fun! :-) aand... sorry for my English, I'm not from an English speaking country :-D
