Print setup plan

Useful setup guidance without pretending STL byte size can predict filament, cost, or print time.

1 model file

Material plan

PETG / ASA

Published material guidance; still check heat, UV, load, and printer compatibility.

Starting setup

25% infill

A planning starting point only; wall count, orientation, and geometry often matter more than infill.

Final totals

Confirm in slicer

Slice the selected model with your final material, orientation, walls, and supports.

Saved setup guidance is used for material, infill, support, and per-file recommendation text; editable numbers are planning estimates only.

Cabin/interior use; avoid high-heat zones

Open the STL, 3MF, or OBJ model in your slicer before printing. Exact grams, time, and final support placement come from the actual slice. Test-fit and heat-check the part before installing it in a vehicle.

Description

Print with large side to bed and no support or raft should be necessary. Quickly built in FreeCAD based on caliper measured dimensions of the original that no longer fit properly. Test printed for sanity, dimensions tweaked on estimate to improve fit - resulting in this usable version. Ultimately I will probably test again to nail the fit - note that I have not checked for wear on the original door lever. Printed in PLA for ease, I think this should be fairly durable but probably best in ABS or PET/PETG as a guess. I'm going to test my new PETG filament for this as a hopefully long term durable part.
