So, Recently, I was asked to design a concept for an already existing project (Ardumower).
The goal of this project is to be able to print it in a 20x20x20 3D printer. of course, this would also cause design difficulties, but also many parts that would need fit be fitted together.
This project will be design after existing Hardware that one can buy from marotronics.
Design concept:
Since the build is already in process let me share some picture of the current status:
The mower can be built either as a single mower or a double version. Your budget can decide. For questions about Hardware or code I refer to (Ardumower).
This is a great project if you want to build your on robot lawnmower.

Re: Ardumower Arctic Hare
Small update:
First rim for the robot is 3D printed. It came out great. The rim will be enclosed by a track with spikes 3D Printed with Flex-filament to reduce ground noise and also makes it easier to change tire pattern. Will also print a Centrum Cap with push- and screw fitting.
This is the design sketch for the Wheel:

Re: Ardumower Arctic Hare
So last night I started my first Flex print. This morning it had failed, Because it partly released from the building surface.
This is my first big flex print.
My settings is:
Filament: PrimaSelect Flex
Temp: 228C
Bed: 100C
Nozzle: 0.6mm
Layers: 0.28mm
First layer height: 0,42
Small prints works great and the result very nice. Any suggestion on how to print large flex prints?

Test assembly of front wheel bracket, mower motors and mower discs. Starting to look good!

Small update:
wheel arches fresh from the printer! All parts is completely untouched and no after finishing.

Re: Ardumower Arctic Hare
Great work. I often have to make large, multi-section prints like these. What would you say has been your biggest lesson or insight from doing such large, complicated/sectioned pieces? Any insight for the rest of us?
Re: Ardumower Arctic Hare
Thanks. This project is designed to be printed in smaller printers (20x20x20) So this made me need to split the body more then I ussaly do.
I always try to split bodies so I can avoid as much support as possible and trying to keep straight cuts, this way I get good adhesion to the print surface from the cut plane. I have no special technique, in usually just do it
