Customizable Razor Stand

My son likes shaving and collecting old razors. Upon completion of USMC boot camp he wanted something to hold a couple in next to the sink. He found this model https://www.thingiverse.com/thing:82968 and asked me to print.

We measured his brush handles and determined that the model needed adjusting to fit. Fortunately an OpenSCAD file was provided so we could make some changes. But it wasn't as easy as we hoped...

This design lets you change the brush holder sizes easily, adjusting all openings accordingly and sizing the stand's depth accordingly.
