Wall mounted key holder in retro-futurist style. It is assembled almost without the use of glue.  A minimum of supports is applied. 
The printing material of your choice, I made from PETG and PLA
Layer height 0.2 mm
When printing hooks, I recommend increasing the number of walls (4 or more), filling density (20-30%) and printing on the side without supports.
Glue will be needed to connect the Frame to the main body of the holder.
