Mini, but not too small, 3D printer that sits on your desk!. It is remixed off of many things, put together to make a 3D printer. As far as I can tell, this machine will need to be tethered during prints so big oopsies there, but this uses a CNC Shield for an Arduino Uno R3, with 28BYJ-48 motors that need to be converted to bipolar motors, and A4988 drivers. An E3D Hotend will be used with the same 28BYJ-48 motors to push filament through, though a Nema motor will be much more efficient, and the machine can be modified to do as such. The design is a standard Cartesian/Cantilever design depending on how i go about it. It has a 50x50mm build volume.
You might need to sand things down in order for them to fit, but dont sand too much as the frame will begin to wobble. Orient things so that minimal supports are required, and where there are supports, remove, and sand it down just a bit to make it smoother. If parts dont fit, send me a DM and I will get back to you as soon as possible, note this machine is still in very early stages of development as of February, 24, 2019. The machine will most likely be done by late spring, or early summer.
