Hi Everybody,
Let me introduce the improvement for my printers farm!
I used to print my projects with Mk3s printers, as they are usually 200mm high… I didn't like that limitation and I preffered the design and price of Mini …so I decided to take it in my hands and modify Mini to meet my requirements of Z axis range (20mm extension was satisfying for me). Therefore I created parts which allowed me to extend the range without any serious modification and high cost.
Now I decided to share it with you, maybe somebody can utilize it for himself.
What is needed to extend your Z axis and enjoy the print volume of 180x180x200:
Screws are needed to replace standard screws, used during assembly of the printer.
Printed parts, I suggest to produce them out of PETG material to conform with the one used for another printed parts in your printer. Parts are being used to move the complete Z+X axes 20mm towards Z+ direction. You should use the top distance to place it between Z motor holder and alu profile and use the bottom distance to stabilize rods and screw on the bottom (please check real pictures). Two cylinders you can create directly in slicer, purpose of them is to support rods.
Don't worry about cables, they are enough long.

CAUTION! Please be aware that you will void your warranty with this modification.
Don't forget to modify Z height in your slicing software.
