On my lack enclosure I use a ribbon cable to connect my Raspberry Pi to my touch screen running Octodash. I needed clips to mount the ribbon cable to the bottom of the lack table. I printed them in PETG because it needs to be flexible for the latch to work. I'm not sure if PLA is flexible enough. I've also included the fusion 360 file if you want to change it. It mounts using #4 wood screws. It prints unfolded using .2 layer height.
