This model was made for those of you who do not want to buy those expensive wall panels. I decided to model these for a similar look and ease of use/installation. 

Measurements/Requirements:

I modeled this to fit the Ender 3 3d printer. That being said most FDM printers out there should be able to fit this model on their print bed. The panels themselves measure 215mm x 215 mm x ~23mm. The connectors are 26mm in diameter and 1mm tall. 

Print Settings I Recommend:

I would highly advise using your fine tuned settings for this print with some tweaks. Most importantly, make sure your bed is level as this print covers your whole bed. As for some tweaks, I would recommend using little or even no infill if you can print overhangs well. This will not only save you filament but also cut down on time to print these panels. Supports are necessary to achieve accuracy in the connector slots. 

Finals Comments:

Please let me know how your prints turn out and if any changes are needed! Happy printing!
