UPDATE: @dempseydiscu_2498555 resized the model to fit a 100x100mm vesa mount and kindly shared it back so now there is a new size available

The ‘base’ fits a 75mm vesa mount (M4 screws), the ‘cables’ has a number of holes that should let through easily also thick hdmi ones, add as many ‘extension’ you need (vented or not) and close it with the ‘cap’

I printed it at 0.2 10% infill, everything with supports except the base

If there is a demand i'll widen the model to fit other vesa standards
