XTool Pro D1 Air Extraction

This is for the 10W XTool Pro D1. The tubing diameter is 23 mm.
The fit of the down tube is very tight. I printed this at 0.16 mm. The reason for this is so that it is a push-fit, rather than using screws etc. to secure. You may need to do a little sanding of the tube to push it in, but I felt this was better than purchasing screws etc. Let me know what you think.
I have also made an adapter to my 4" (101.6mm) extraction fan. Let me also know if I should include this.
