Prints within 2.5 hours each. And the cover prints normally without any supports and takes about 4 hours. 9 hours total print time. No hardware necessary for install. Just slots into the duct very easily and then held together by the fan itself. Works great for HVAC in old homes where the upstairs is always 6 degrees off the main floor. There are some duct boosters in the market that costs over 65 bucks, but has very low power - only about 70 CFM. This is great because: 1 - Control from the room 2 - Low noise and low power (45W) 3 - 420 CFM!!! 4 - Suction is more efficient in old houses, since boosting from basement is less effective 5 - Easy 1 minute installation 6 - No screws / hardware required - just slots into the vent 7 - Fan is a 8” Grow Fan from Homedepot - $30 each 8 - Literally blows the competition away - LOL 9 - When you move, just take it with you If you like what I do, buy me a coffee from the link below. :-) http://paypal.me/avicode
