The main idea of this printer is to create a new design of a 3D printer with a cubic cartesian scheme which includes as many as possible parts from plastic. I.e. it supports the RepRap concept to create some kind of easy reproducible 3d printer to make it more achievable for a wide engineer society. One of the main concepts is that all plastic parts designed to be printed by one hotend 3d printer without using supports.

The following is a list of the main improvements made upon the Prusa Mendel Iteration 2
- Enhanced frame rigidity (prevents x-axis backlash)
- Easy assembly
- Parametric files for multiple sizes/bearings or bushings
This is the first version that represents the nominal configuration. Several parts planned to be developed such as a cable holder, filament roller holders, ventilation system for hotends. The development of the GLKLN is hosted on the: .
files for the printed parts are available on the: .

The updated version of the BOM can be downloaded from the project repository on the: 
The GLKLN uses, including the two extruders, 6 stepper motors. Two of these motors, the Z-axis motors, are connected to the same stepper driver of the electronics.
The GLKLN uses MKS Gen L motherboard. Because RepRap printers compatibility it can be based on the other RepRap controller boards.
