I really like TownDrunk's housing for the Super Racer (IMO it's the best one available for the printer - clamping extruder horizontally or using separate adapters for 5015 fans isn't great), but it was only available for the Orbiter or Sherpa. Since he's made the CAD files available, here is a quick edit of the adapter plate for the LGX Lite.
Also included is a helper plate you can use to cut your PTFE tube to the exact neccessary length. Just pop it on before mounting the extruder, cut flush, then mount and assemble.
