Hey there.
Here is my minimalistic version of a pictureframe.
It is meant to hold 10 cm x 15 cm pictures which should equalivent to 4 x 6 inch.
Please have a look. There are more designs than the ones pictured.
Feel free to wish more designs in the comment section.
Base is printed solid to give a small stand and wheight.
After that print in vasemode with linethickness 0,7 mm.
A 0.4 Nozzle will do fine.
Scalings:
13 cm wide picture → X/Y → 88%
7 inch wide pictures → X/Y → 120%
