USB Power 6in Rack

Designed a USB power bank holder for a 6in rack. The power bank is 30mm tall, 125mm wide and 75mm deep. Any power bank that meets these sizes will work. Over the tray are two arms that strengthen the tray, but also hold the power bank in place. The insert was designed to work with the 6in version of: https://makerworld.com/en/models/1063100-3d-printable-rack-10-inch-and-6-inch#profileId-1051689 but any 6in rack will work.Print in PETG for some added flexibility and strength, but PLA will work fine. If your power bank gets hot, advise NOT using this (and maybe not using the power bank at all) Included in the files is the FreeCAD 1.0.x file for extension or changes if desired.
