Desktop multi device vertical organiser

I made this desktop organiser to hold different devices such as a mechanical keyboard and latops/ipads as I did not see any available. This stand can hold up to 3 devices, the first is able to hold devices up to 35mm with a nook to prevent sliding, and the 2 behind are 20mm which can hold macbooks with cases and ipads with cases easily. I have originally printed this on a P2S in PETG and have not tried PLA. So far it seems strong enough and is able to support the devices without any issue. There is one issue as the rear has overhanging that will require supports, to be used, the gap is required incase it needs to overlap with monitor stands etc. Let me know your thoughts if you printed them and feel free to share your prints/ how you use them
