Sanding quite a lot of drywall joint setting compound was filling my house with dust. Didn't want to shell out $12 for the commercial adapter (006) so I modeled up my own. Colored in the bag adapter end with a Sharpie to make a print onto a sheet of paper. Scanned as a PDF, opened in AutoCAD to slap on some rough dimeio to get started. Modeled short rings for the sander end & hose end in Solidworks. Tweaked to get the fit right. Lofted a smooth blend between the final shapes. Finished my sanding work without filling the house with dust!
