This simple stand is designed in Fusion360. 

The design of this organizer/stand is flexible space to accommodate pencils but also business cards and other paper notes. In the end it looks in this color like chocolate bar.

I printed it on my Prusa Mini+ with 0,4mm nozzle and 0,2mm layer height. I used lightning infill of 15percent to speed it up a little. Filament used in foto is Prusament Mystic brown. 

I hope you will enjoy this model and I cant wait to see prints in different colors in comments! Maybe gray as if it was from concrete?
