PHOBIUM is an aggressive-looking Blade Plug Designed to be adaptable to any socket size. Files are available as .stl for 1" and 7/8" plus source .f3d files for Fusion 360 so you can make any adjustments needed.
This is really meant to be printed in black with a white base or insert, but I'm sure it would look ok in other colours. The Plug portion needs to be printed with supports the Base and Insert do not need any support
it is recommended to print this with at least a 0.1mm layer height
