My first 3d model and first print from my Anycubic Vyper I probably should have started with the owl

In theory you have the Vyper so perhaps skip right to the gcode...

Included the STL and a 95% decimated STL

Also included an STL of the profile in case you want to make your own without wasting as much time as I did getting the dimensions right.

I hope it works for you

131mm tall 76mm wide 13mm beveled corners

walls about 2.5mm thick thinner in the beveled corners
