sockle for spool support

I wanted to make s support for my spool and like the one Steve Carmichae made, at the start of the video, his spool support caught my eye, so did his whole project.!! (https://youtu.be/l2KTRjbPpQ4)
I don't have his fairy wood working fingers but I had a go!
I used some 40mm (1 1/2 ") plastic pipes I had laying around the shed but needed a way to fix the whole gizmo on top of my enclosure.
I designed using ProgeCAD (http://www.progesoft.com/) which enable me to export directly into a STL file.
