A minimalist holder for the 3x3 sticky notepad, a pen, and a daily note. Has four bottom recesses for 1.5mm cork or rubber for non-slippage.

The Fusion 360 file has a pen_hole_diameter parameter that lets you adjust for your own pen. The pictured model has a 10mm pen hole diameter that fits the BIC Round Stic (8.5mm diameter). You should adjust the pen_hole_diameter parameter to be 1.5mm larger than your pen diameter to allow the pen to easily slide in and out of the holder without getting stuck.

Printed at 0.12 layer height with a brim to keep the warping under control.
