Identical to the original model this is based off of, except that the PG7 hole on the side of the housing is fully threaded.
I had the best luck printing with the small opening touching the bed, I know it doesn't make sense based on the direction of the PG7 hole support structure but this is a quick remix, and I may fix that in the future :) Due to that oddity you will need to use support for the PG7 hole, and could probably benefit from some support on the fan hole bridge.
The author remixed this model.
