3d printer

Magnetic Print Bed

This is a Magnetic print bed that can be installed on a 3D printer for better adhesion and also so your finished prints can be easily removed. A while back I installed a similar print bed on my main 3D printer, but did not document it apart from some posts on Twitter. In this post I will cover the installation in more detail.

PSU grip

Power Supply Unit (PSU) for the 3D printer is usually a large block that floats around the desk and is not connected to the printer. It is usually forgotten to integrate into the design. If you are lucky you can find mods on Thingiverse, but I had no luck and had to design one myself.

Build a 3D printer - Part 12: Power supply

After hooking up of all the connections to the RAMPS 1.4 board we will need to provide power to the board. The standard 5V output of the USB connector is only sufficient to power the Arduino and the LCD display, so we will need external power. The minimum power that needs to be provided is 12V x 20A (240W). But just to be sure we will use a 12V x 30A (360W) power supply.
