This replaces the mechanism of a tm500 door handle for RV cargo handle measuring 5" by 4.5". (Might fit others too)
Original part are 3 white prongs with snap in/friction connection.

I couldn't find the replacement part alone nor a seller who can sell in Canada for a reasonable price, so I had to make them.

Those part replace them to push the lever in case they broke.

M4x8 threaded screw hole to add a washer in case you don't trust the friction fit.

Here's the original handle that fit this reworked print: https://rveliteparts.com/products/rev-rv-10117815-compartment-door-latch-tm500?pr_prod_strat=use_description&pr_rec_id=9c6988bab&pr_rec_pid=7764903035099&pr_ref_pid=7883140563163&pr_seq=uniform
