The file 'Balununun Box!! 3D Printer Model' is (stl) file type, size is 1.9MB.

Summary

A simple box for mounting an FT240-43 (or similar) toroid transformer / balun / unun or whatever..
Uses M5 mounting bolts in the relevant holes, and an SO-239 chassis connector..
There is a blanked off hole on the "base" for a grounding bolt if needed..
Plenty of info on Facebook for end fed half wave antennas... (EFHW)
I've put the lid and base as separate files, as together they may be too big for your print bed..
EDIT :
I have added a deep box for stacked toroids as requested..
