Customisable Prusa i3 MK2 Rambo / Controller case - DOOR

You Don't Need Firmware??\r\nIf you're building a MK2 clone with a RAMPS based board, you've got yourself a MK42, and then you might want to run a port of the prusa firmware. See https://github.com/slippyr4/Prusa-Firmware\r\n\r\n## What is This?\r\n\r\nThis is a customizable, parameterized rework of the Original Prusa i3 MK2 case. Find the original in Prusa's github repository at https://github.com/prusa3d/Original-Prusa-i3/tree/MK2\r\n\r\nThe original SCAD was designed around the Rambo Mini 1.3 board, but I wanted to use a different board. So I reworked the SCAD file to make the board dimensions into parameters so it can work with many different controller boards.\r\n\r\nYou need to enter the length and width of the PCB of your controller board, and the offset from the board edge to the mounting holes. There are two more parameters which are optional - top gap - which adds extra spacing between the PCB and the top of the case. That's not needed on the RAMBO mini, but a value of 6 works well for MKS boards. There's also an HBP offset parameter which optionally moves the HBP cable entry assembly up or down. This was needed for the MKS base because the original location of the HBP cable entry fouled the USB socket.\r\n\r\nThe RAMBO mini has the USB cutout on the top edge, that's deleted from this design. I've not added the facility to put a new cutout for your board in this customizer. You could download the SCAD and do it yourself, or just get handy with a scalpel when you've printed it.\r\n\r\nI recommend you print in PETG if you can, but any plastic would do.\r\n\r\nIf you print this you will also need to print the BASE (see https://www.thingiverse.com/thing:2370602) and also the hinges (which are unchanged from the prusa original). When customizing the BASE part, use the exact same values for the parameters as here, or it won't line up and fit.\r\n\r\nTo help you out:-\r\n\r\n### MKS SBASE\r\n> Board Length 146.5\r\n> Hole Offset 4\r\n> Board Width 95\r\n> Top Gap 6\r\n> HBP Offset 0\r\n\r\n### MKS Base\r\n> Board Length 110\r\n> Hole Offset 5\r\n> Board Width 90\r\n> Top Gap 0\r\n> HBP Offset -6\r\n\r\n\r\n### RAMBO mini\r\n> Board Length 103\r\n> Hole Offset 4\r\n> Board Width 69\r\n> Top Gap 0\r\n> HBP Offset 0
