Flexi Rex keychain (hidden loop)

This is a remix to our previous design: [Flexi-rex with hole for keychain](https://www.thingiverse.com/thing:2776182)

The main reason we made this remix is because we received a number of
feedback regarding to the loop (in our previous design) felt off easily during/after
print, hope this design can fix the problem. =)

*No supports is needed*
*else the keychain loop might filled with supports, hard to remove"
*Printed with brim*

Tried scaled and printed with 80% size, the keychain can hardly fit in,
85% is just nice if you are thinking of printing a smaller one.

Have fun printing!
