​
The ultimate printer I can recommend is the Bamboo Labs X1 carbon with AMS if you have deep pockets. ($1200). It's a massive leap forward in 3D printing, with excellent quality and impressive speeds. Its pretty much press print and go as the software and hardware do the calibration before each print. This printer will not manage the larger parts and you are going to need the CREALITY CR10 v3, which is my second choice of printer.
​

This design is a remake of the $38 DIY MCP. It's a newer, better version taking full advantage of 3d printing. This is not an exact replica but it is fully functional. The design has been modified specifically for 3D printing. The text is larger, This helps to produce good quality, clear and crisp text. Various components have been moved to allow easy fitment. All parts assemble with ease and require no additional mounting hardware other than their own attachment nuts and screws. Also, full 7219 boards are used, so the wiring is much easier! Backlighting has been removed for simplicity and may see a return in a more complex version later on.
This design requires a minimum print size of 220mm x 220mm. But for a really good overall finish, I would highly recommend a bed size of 300mm x 300mm
