Headphone Holder - Picture Wall

View years ago we bought a picture wall from butlers. The pictures have to be bent a little so that they are tensioned and so they are then clamped between the strips.

The photwall is behind my office desk at home - so i designed a headphone holder which slides into this wooden stripes. 

There are two versions available - one longer and one shorter. 

The print is in Prusa PETG and takes about 50 Minutes in draft.
