TR8 Lead screw nut housing

I had to buy one of these for a project I'm doing. While I am waiting for the piece to be shipped, I wanted to make a model of it to test fitment on the parts since it will be about a month before it arrives. I used tinkercad to design the model

Overall dimensions are 34x30x28mm. Center is 10.3mm. Holes for the lead screw nut are 16mm apart from centers. The indentation is 22mm diameter. Screw holes for the nut are 2.5mm diameter. The holes for mounting the bracket are 3mm diameter.
