Description

This Thing is a replacement for the main gearbox body for the trunk lid pull-down assembly in my 1992 Cadillac deVille, reverse-engineered from the original part (as mine broke in several places, due to age and excessive mechanical stress). It supposedly fits other deVilles from 1985 to 1999, and may fit some other makes and models also (I am not entirely sure). This is just the gearbox casing, with the motor cover separated-out into a bolt-on unit (you can see the broken-and-reglued original part at the end of the photo list), so you will need several of the original parts to make use of these files: the motor and brush assembly the little black corner piece that goes behind the brush assembly's connector tabs the little cap from the end of the motor rotor spindle (its a simple sleeve/sliding bearing; you'll have to press it out of the original part with a small screwdriver) the pull-down loop assembly with thrust bearing, lifter gear, and spring washer the limiter switch assembly The three large main mounting screws. You can re-use all of the original screws to put this together (four new screws will still be needed), but I designed this so that proper machine screws and nuts can be used instead, as I dislike screws just biting into plastic to hold things together (especially on 3d-printed parts) if there's another way. Theoretically, the brush assembly, lifting gear, that little black corner piece, and most of the limiter switch assembly could also be replaced with 3d-printed parts, but mine were in good shape, so I re-used them. I do not plan to create models for these. Update 2018-08-02: My part split along layer lines because it was printed too cold and with too much fan. After seeing where it split, here's a new version (specifically, of the gearbox part) with thicker walls around the motor spindle, and slightly larger holes for the main mounting screws.
