Here you can get bookholder for your Skadis pegboard with 20-80mm width.
You need to print at least 2 holder for one book, as seen in the picture.
The back part of the hook has to be flexed to securely fit on the pegboard.
I used PETG filament, other materials are surely possible.
Just make sure, that your parts do not get to brittle.
If you still have problems and the the pegs are to wide, scale the whole thing down (2-3% at a time) in z (height) until they fit right in.
If you want different dimensions please contact me.
The author marked this model as their own original creation.
