Spark Plug Holder
thingiverse
Off the shelf products didn't fit my needs, so I made this. I went through several tests to get the threads to have enough clearance on my Elegoo Neptune 2s. Hopefully it will also work on your application. I made a few adjustments to the design since I printed it to give a bit more room for the threaded portion of the plug. This shouldn't effect that overall print. I recommend printing the pieces one at a time in an upright fashion (threads on top) so that there is less likelihood of the threads getting screwed up. You should be able to print without supports. Enjoy!
