This is a cable gland of the type where "fingers" are pressed against a gasket by a cap.
The nut attached to the core of the gland is supposed to be used when screwing on the cap while the loose nut is used to attach the gland core to box from the inside.
Most important parameters are given in a spreadsheet in the supplied FreeCAD document. Probably, you will want to reduce the length of the core (which is currently 20 mm, corresponding to a common component size). Obviously, this value should be adjusted upwards for thicker walls.
Update 2018-02-08:
All files have been updated. The cap and nut dimensions have been modified to give higher strength. The previous version had a problem with the top of the cap easily breaking off when printed with PLA.

Infill:
20%
Notes:
Consider Nylon instead of PLA for increased strength. Due to Nylon shrinking, cap radius might need to be adjusted upwards.
The gasketcould be printed in a flexible material but would then need to have a low shore hardness, perhaps like that of Ninjaflex. Otherwise, you could try to cut a piece of 7x11 or 8x11 latex tubing.
I printed all partswithout supports. I could print the gland core without supports since I had placed the attached nut att Z = 0, but with other Z (like in the uploaded files), supports are required for the core as well.
