Vertical build plate holder with push button ejection

prusaprinters

First remix, and first shared model. plz be kind. I wanted a plate holder, but kinda wanted something trick. So, found a sheet holder that used buttons and mixed it up a bit. I modified this to use less plastic, be mountable vertically, and have a measuring tool that can be used in the final install as well (To hide the button rods, if exposed mechanics isn't your thing). Printable in just about every filament, and can be printed without supports. It's recommended to print both sides of rails vertically so that the button guides stay dimensionally good without sag (Which happened to me on the first print of the original: the interior channels sagged down, making it impossible to install the rods). Buttons will need to be printed at an angle to fit on the mk3/mk4 size plates. All parts of the plate holder can be printed on a single plate. Oh, buttons are keyed. Please note this during print and install: There's one side of the smaller button part that lays flat against the sheet during printing. This side that touches the build plate will also fit in specifically when installing the rods. It will make sense when put together.
