Slatwall book shelf

This is a shelf for a slatwall. My library had been purchasing shelves from Demco, and something changed in Demco's newest version where they were too tight a fit and they would often break when trying to remove and them.

I print these on a Bambu Lab A1, PLA, 0.3mm Layer height, no supports, no brim, and it takes ~2 hours to print and uses ~70g of filament.
