Powerbank hanger for puluz grip

I have this puluz camera grip: https://www.puluz.com/p/PU3006/PULUZ-U-C-Shape-3-Head-Cold-Shoes-Portable-Handheld-DV-Bracket-Stabilizer-Kit-with-Cold-Shoe-Tripod-.htm as well as an Anker Powercore Select 20000 power bank. 

This is a part when printed allows you to hang the powerbank from the legs of the grip. I printed two of these in PETG and slid them on the rails, one from the front and one from the back. Legs are spaced to allow you to mount on a quick connect tripod base if needed.
