3D printed arbor press

I am learning how to use FreeCAD and wanted to challenge myself to see if I could create something that I could use for helping me with other 3D prints (I use a lot of press-fit things). The arbor press came to mind, so here is my attempt at making one! Here is a diagram of where all of the heat set inserts and the M3 machine screws (6mm and 20mm) are on the arbor press: I'm still getting used to doing proper drawings for instructions, so this is going to have to do for now.
