Do some 3D Modelling

Working with an existing STEP file Please add more plastic left side of the cup, leaving 1mm gap only, same applies to iPhone 6, right now the gap is too large The gap where the phone is inserted should be 78.5mm instead of the current 77mm (iPhone 5) The guides touch the side of the phones and end up touching the buttons, so we shoud reduce their height by 150mm (1.5 cm) The hole for iPhone 6 should be expanded upwards and downwards by 2mm and to the right by 2mm When you're doing the above work, please don't forget about the tiny guide we have running around the hole, it should be left in place Lets expand the top of the cup by 5mm upwards and the cover by 3mm downwards so there's more surface area for the cover to grip view of the cover
