This pencil holder has a square design with rounded corners and offers a total of 49 holes, primarily for 12mm diameter pens. For brushes with thicker shafts it might be a bit tight. The model was made from PLA filament and printed with a 0.4 mm nozzle at a layer height of 0.2 mm. No support structures were used, nor was the model given a particularly high degree of infill (15% infill). Thanks to the rounded corners, the holder can be easily moved around without leaving scratches on the desk, making it ideal for both professional workstations and creative craft areas.
