Snap-on Duo iPhone case

I have a personal phone(iPhone 17 pro) and a work phone(iPhone 15 pro).For most of time I need to carry them together.Sometime I only need to carry one of them.So I created this model to build cases that can snap together or separateI'm planning to print it with TPU but I haven't got my material yet.Remixed from [1] https://makerworld.com/en/models/1830096-iphone-17-pro-tpu-full-coverage-phone-case?from=search#profileId-1954172[2] https://makerworld.com/en/models/798794-iphone-15-pro-tpu-case?from=search#profileId-738392[3] https://makerworld.com/en/models/1085445-snap-on-box?from=search#profileId-1078147Disclaimer: I haven't printed them yet so it may cause some problems.
