Replacement armrest / door closer handle for the 1990s era Ford F-150. Don't bother searching the junkyards for a good salvage one, they all broke over the years. A bit of a poor design really.
-- These are NOT a perfect show truck fit. --- They are a good start for you. ;-)
I have a rusty 33yr old work truck that still works. Spray glue a layer of foam for comfort and cover with a free material.

Made with SUNLU, PLA+ @ 35% infill, 11 hour print time each side. Holds staples from a regular staple gun when pulling the fabric cover tight.
Total repair cost about $6.00
