I printed it with 1.6mm shell thickness and 10% infill.
The holes for wall mounting are 350mm from each other.
For bigger printers with 400x400mm print beds I uploaded a single piece model and a slim version.
UPDATE
The slim version can be printed on the Prusa XL too and now I uploaded a slightly changed standard version that can be printed on the Prusa XL. (different hole spacing… 330mm)
The author marked this model as their own original creation.
