I left it in its housing the actual part as shown separate is easily removed from that housing (I left it for protection or might fit your printer like that too).
You do need torx style bit t10 i think to remove the screws.
I mark my items to prevent fraud and returns that are not the same. If you do try this just know for others sellers sake I take it very seriously I don't mind a neg response if it prevents someone from trying to do it again. sides with me as I have proof. This is only a problem with fraudulent buyers, I take care of my buyers. Just don't try that.
