Clip on Lens Cap for Fujifilm X100 Series Hood

This cap is designed for this hood:  Fuji X100 Serie Square Lens Hood by VZPHOTO - Thingiverse
The cap for this thing can be clipped on the hood, not friction fit. It needs to be assembled.

I recommend printing the spring part in PETG.
 

Steps for assembly:

put one side of the spring into the slots on the cap, then compress the other side and squeeze the other side in. Make sure to slide the central ring onto the pin on the cap.
Align the lid for the cap and use tiny drops of superglue to glue it on. Try not to put too much on, or the superglue might flow into the spring slots.
