About this 3D model

I figured I'd design a hermera (with Volcano hotend) mount for the railcore. All of the parts with inserts are designed to be used with M3 inserts with a 5.15mm OD (https://smile.amazon.com/gp/product/B077CJV3Z9). If you want to modify this design let me know and I'll upload the solidworks/stp files. I included a picture of roughly how it should be sliced, but a petg or pc carbon fiber filament is recommended as filament (in the screenshot pla is chosen just for a test fit).
