I've included a mini frame for this. It prints in less than an hour and the print can be superglued to the frame or I have been using glue dots that are mostly used in scrapbooking. The frame prints great with the satndard .2 print profile.

Print at 100% infill with a layer height of 0.08mm with a base layer of 0.16mm

The Model is 200x133.33mm in size
You may print at higher layer heights below the Base Thickness of 0.48mm
The Max allowed Thickness is 2.24mm and the Actual Thickness is 1.44mm

    #000000 PLA BambuLab Basic Black  Transmission Distance: 0.6
    #003b3b PLA BambuLab Basic Green  Transmission Distance: 2
    #fce300 PLA BambuLab Basic Yellow  Transmission Distance: 6
