Printrboard to SKR E3 adapter plate

thingiverse

This is an adapter plate to bridge from a Printrboard to a SKR Mini E3 V1.2 board. The upgrade is for a printrbot Play 3D Printer. The adapter plate was designed to offset the SKR board, moving the MicroSD and MiniB USB ports closer to the printer sidewall. To access these ports, a hole must be cut into the side of the printer. Access to the MicroSD is necessary to run the printer standalone or through a computer using USB. Another option is to use the TFT35 E3 V3.0 touchscreen with the SKR Board. This setup includes full-size SD and USB ports for reading media files for prints. For my adapter, I'm using an Ender 3 pro screen, so I need to use the MicroSD port on the board. I replaced the Molex connectors with JST-XH connectors needed for the SKR board. Note: I've added a version that nearly centers the SKR board in the printer. If you plan to use one of the TFT screens with built-in SD ports, use printrboard to SKR Mini3.stl instead. You'll still likely need to dismount the board for firmware updates. This version may also allow a MicroSD to MicroSD or MicroSD to SD extension without cutting a port into the printer body. I'd like to make this board larger to accommodate things like the adaptrboard set. Unfortunately, the Y Switch leads are very short, barely fitting now. To do this, you'd need to lengthen the wires. I may try this anyway to see what mounting space is possible. There's a lot of space under the board adapter for mounting the adaptrboards directly to the body, making it an option for those looking for a place to mount them. The boards come with 100mm leads from the SKR to the adaptrboards. Then you plug in the connectors to complete the conversion. Update: I've added another version of the Play adapter (printrboard to SKR Mini5.stl). This one lines up the MicroSD on the board with the MicroSD port already in the Play chassis, leaving the USB port blocked but requiring less cutting to expose it.
