Distance between hole should be 25mm. You can insert 1.75mm filament with pliers to the peg hole to ensure the stability.
38mm x 12mm paper will fit. Visible area is 30mm x 12mm.
Do not create support to the tiny holes.
UPDATE 2022/02/04
cut filament to 13mm and sharpen one side. Then put it into knob and insert to the small hole!
