ToyREP Documentation


On this page you will find detailed list of printer parts. As ToyREP 3D printer is quite modular, this page serves as a guide for the default set-up.


Most of the parts mentioned here can be obtained on internet. Best princes are usually on Chinese e-shops. These parts may suffice as their functionality is almost the same as of originals, but sometimes may happened that they are somehow faulty. The fault is usually not obvious for the first sight. In my experience it was for eg. PCB heatbed that did not have required resistance, so it was not reaching desired temperature or 608ZZ bearing that did not have the bore hole exactly in the centre. If you are looking for the best price you will have to live with the fact, that some parts will have to be ordered repeatedly.


I am sorry for any mistakes that may appear in any documentations for the printer and would like to ask you kindly to give me a notice of any problem you will find on thorgal(at)atlas(dot)cz. Despite my genuine regret I cannot be held responsible for any loses or injuries caused by calibration or operation of the ToyREP 3D printer.


Parts for default set-up with embedded 111x78x36mm big PSU, Arduino Mega 2560 with RAMPS 1.4, 100x100x100mm big print volume, short throw geared extruder for 1.75mm filament with E3D clone hotend, 120x120x3mm polycarbonate sheet as cold bed.
