Parametric 16 Valve Engine Head Disassembly Tray / Parts Organizer

thingiverse

I wanted one of these trays for a project and noticed they cost a small fortune to buy online. It's just a simple plastic organizer so I decided to make my own. The provided default values are to fit a Toyota 5S-FE but if you know the measurements of your parts you can customize it to work with any 1, 2, or 4 cylinder engine with 4 valves per cylinder. I recommend using MeshMixer to plane cut it in half for printing unless you have a very large printer, and you can also cut it down to 1 cyl if you like. I will provide a pre-cut generic STL. The tray has sockets for all valves and springs, plus an extra parts dish per valve (optional) to put in keepers, shims, etc... if you need it. If you don't want these dishes you can make the print smaller by entering 0 for the dish diameter value. This is my first openscad project so expect the code to be messy and probably doing things the hard way. Rendering time can be quite high, so I recommend downloading the source and running it locally. I recommend PETG for superior chemical resistance but PLA or ABS should do in a pinch as long as you avoid spilling solvents or fuel on it.
