Mac Book Pro USB-C Coupler

I wanted to make something that attached the charging cable (USB-C) and a UCB-C to HDMI addapter (Cable Matters 48Gbps USB C to HDMI 2.1) together to make docking my laptop almost one plug as there was now power pass through on the HDMI addapter but the plug cassings where 2 different sizes so I thought I and the only other one I could find on MakerWorld was for 2 cables that where the same size. This was modeled using TinkerCAD and is the first thing I have designed from scratch.I Printed It in PLA as that is all I have to hand and it is clamped to the plugs using an M2*10 and M2 nut.
