3.5" Touch Screen Mod for Prusa Mk2/2s/3/3s - OLED Haribo Mod

prusaprinters

I have a Haribo MK2.5S build and was also looking to swap my LCD for an OLED display. Modded the STLs in Fusion 360 to reduce and inset the LCD display hole since the OLED is thinner by about 5.5mm. Also edited the text to make it Haribo edition as well as created a 2nd STL that is text only for dual color printing via a method of your choosing. The text is .6mm thick and I need to do it with a single extruder through manual filament change. Printing at .2mm layers ensures I only need to stick around for 6 color changes. Nothing else was changed so the remaining original parts in the parent model will be the same. The oled screen used is “Winstar WEH002004AWPP5N00000” and soldered to this controller board: https://www.printedsolid.com/products/ldo-prusa-mk2-mk2-5-mk3-display-controller-no-lcd which is identical to the prusa stock board just minus the LCD. It has a pin header you can install a new LCD onto. I am using these instructions as this LCD also requires modified firmware: https://vmod.wordpress.com/2018/12/02/mk2s-oled-screen-replacement/ (DOES NOT WORK ON MK2.5 or newer) Edit 3/20/19: Added a blank frame. Edit: 08/01/2019: Setting model to final as I had been using this successfully for some time. However, this is purely a model for those who want to do the work to make the OLED mod work. Members of a Facebook ended up making a MK2.5 compatible set of mod files to make it work but as of Prusa Firmware 3.7.2 the firmware fails to compile with the mod again rendering the OLED inoperable. I'm falling back to the stock LCD but am keeping this model up for those who make it work themselves. I would appreciate it of you drop a comment if you have a way to make it work on 3.7.2.
