​
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.
​

I'm excited to present to you a new and improved version of the $38 DIY MCP design that fully utilizes 3D printing technology. Although it's not an exact copy, this design is fully functional and has been modified specifically for 3D printing. One of the key modifications is that the text is now larger, resulting in clear and crisp text. Additionally, various components have been strategically repositioned for easy fitment. Assembly is a breeze and requires no additional mounting hardware other than their own attachment nuts and screws. The wiring is also much easier, thanks to the use of full 7219 boards. To simplify the design, backlighting has been removed, but it may be added in a more complex version in the future.
The unit is larger compared to the real aircraft version, measuring 490 x 89mm, which was done to enable the use of full-size components and enlarged 3D printed text.
To print this design, a minimum print size of 220mm x 220mm is required. However, for the best overall finish, I highly recommend using a bed size of 300mm x 300mm.
