A remix of tlamp's 4" vent adapter, this version features a shorter funnel but retains a wide recessed band for securely attaching ducting/vent hose to it. Snaps straight into the air filter slot, no screws required.
Original model is plain, second model includes a “top” marker to aid insertion.
Printed in PETG with tree supports (build plate only) and no brim. Infill not really required but printer was set to 15% Gyroid infill.
The author remixed this model.
This remix has a much shorter funnel but retains a wide band for securely attaching 4 inch ducting.
