This is newer version we created to fit a 4 inch (see more here: https://amzn.to/2vHCXUf ) dryer vent hose for the 1 HP fun house blower (see more here: https://amzn.to/36Rwin7 ) we use to evacuate fumes from the eBay/k40 CO2 Laser (see more here: http://diy3dtech.com/purchase-laser/ ) we use in the shop. This is a two piece print to make it easier and has a snap fit (you can add glue if you want but don't need to). We have also included the Fusion file so you can make changes if you need for your blower! We used a Clear Silicone Waterproof Sealant (see more here: https://amzn.to/37VvuPw ) to attach the adapter to the blower. The reason for using Clear Silicone Waterproof Sealant rather then say a glue or epoxy is so if want to change it in the future we can just score it with a blade and pop it off without damaging the housing of the blower.
