4x1 Gridfinity Single Pen Holder

It's my first ever Shapr3D model - very simple, I learned how to make chamfers, remixed using a 4x1 blank Gridfinity base. The idea is that this would be the item on the first layer of the Gridfinity for the pen that I was initially using, and having the a box of the same size of the same pens underneath. At first I included finger holes for removal, and then thought it looked a bit rude, and added the press down at the edge to be able to easily access instead. It's Bambu dark blue matte - I really like the colour.
