Printer and completed cabinet

What I did

Built a cabinet to support the printer and integrate the ventilation route with the workspace.
Modelled custom interfaces around the printer outlet fan and cabinet. Non-standard design was used for the duct support connection.
Used a portable-AC accordion duct and a window outlet with a HEPA filter to route the exhaust outside.
