Camera Bed Mount for Maker select Plus

I wanted to mount my camera on the hot-bed using the amazing camera mounting arm here - https://www.thingiverse.com/thing:3114849
I have a monoprice maker select plus which is a rebranded wanhao i3 plus.
This mount builds on the idea I took from https://www.thingiverse.com/thing:3538544 and modified to fit my bed which is 3mm thick and uses a spring stabilizer cup ( https://www.thingiverse.com/thing:2597193 ). So I designed it accordingly to fit nice and tight.

There are two lengths, 90mm
