Vacuum hose adapter for use with Makita BO4550 or similar finishing sander. Inlet measures 10.5mm x 32.2mm for reference. Fits 2-1/2" vacuum hose.
If you need a different size vacuum hose port, drop a comment with dimensions.
Edit: Added 35mm version per request.
Edit: Corrected an oddity causing issues when slicing with Cura on both models.
