Gridfinity Power Bank Holder

This is a Gridfinity storage unit for an Anker 20,000 mAh power bank. The powerbank fits snugly in the cut-out. I created this as I recently got it for Christmas and I'm trying to keep my desk tidy! The cut-out dimensions are approximately 26.5 x 74 x 157.5 mm, with fillets on the corners. This occupies a 1x4 gridfinity slot.
