Simple Pencil Holder

This is a simple, no-frills pencil holder, designed for a singular pencil to be put on display and be easily accessible. I was looking for a such a thing to hold my Uni Shift Pipe Lock drafting pencil, but everything I came across was either designed for more than one pencil, or had extra visual features that did not fit into the minimalist design I was looking for. The central hole that holds the pencil is 7/16 inch in diameter by default, so if your pencil has a grip of less than that diameter, it is likely to fit. I can confirm that it fits not only a Uni Shift Pipe Lock 0.5 mm and a Zebra Delguard Type-LX 0.5mm, of which pictures are included, but also a Pentel GraphGear 1000 0.5 mm. I will most likely work with different lead variants of these pencils, but I cannot confirm. I have also attached the FreeCAD model files, in case you need to modify that diameter. Instructions are included within a note along with the file.
