I don't want to clutter up @caain
's thread where I posted this first, and it's kinda based on the model here, so I'll just put this here too.
This is the onShape share link
to all the files if you missed it in the other thread. And this is what the initial idea looked like:
The model is maybe finished now. Still need to make a complete one to test. Should be about 4-5 hours print time for all 5 parts. Here's what testing the button openings looked like:
I forgot to scale it up by the 2% shrink factor. Oops. The buttons will fit in there if a bit tight. They work and the truck will lock/unlock as normal. Maybe the tightness will help with keeping water out? Oh, I cancelled that print after only 10 layers. The real one has the buttons much closer to flush across the top.
Here's what I did to make the handles look a little less dumb:
It's 2-1/2" tall, it's hard to make a keychain-size gas can not look a bit cartoony. I want to get some black for the cap and red for the rest. Right now all I have is blue. It will need (4) 6-32x3/8" button head screws to assemble. There's also room on the back if you want to add name engraving or whatever. I left it plain for now.
EDIT: attached a ZIP file with the 5 STL files if you want to make one and don't want to deal with exporting from onShape.
EDIT 2: don't use this file, go to post #40
for the updates
