D22 Navara ashtray replacer

thingiverse

My adventure vehicle is a 2005 Nissan D22 Navara. Soon after purchase I removed the whole ashtray mechanism and decided to create something to fill the open ashtray holes. I want to add a friendly horn system to my car where one button can play a friendly sound through a horn speaker (like the C3PO noise) to alert people to my presence in a less threatening way than tooting the standard car horn, another button to 'double-toot' the horn, another button to activate air horns, etc. Refer to the photos as part of the description. The switches that I used are momentary action push-buttons purchased from Jaycar (Australian Electronics supplier). The mounting holes are 20mm in diameter to suit these switches, but anything that fits in a 20mm hole can be mounted). There is one single mounting screw to hold the part from behind the facia. The screw that I used is about 10mm in total length, and about 3mm in shaft diameter (including thread). I had to place a washer under the screw head. The screw tapped it's own thread into the 3D printed part. At the bottom I created a foot to rest against a flat section inside the cars facia. You can choose to use glue/double-sided tape/polyurethane, etc to fix it there, but I found that for my use it didn't need anything other than the screw. The part fits into the facia quite snugly but with a small gap at the bottom. I used Fusion 360 (2.0.8816) to crudely design this. I used Cura slicer to slice and to also mirror the part for the LHS. I printed it on my modified Creality Ender 3 Pro.
