Think it will work? Real ones seem to sell for more than $1, flattened bottle caps might work, but so might this. How hot does it get down there?

 

With a torch next to the plastic nut. It got hot, started to flame. So, not worth a risk of a fire underneath. I’ll either try to find affordable ones, or experiment with flattened beer bottle caps. No shortage here.

 

You could probably do PEEK if your printer can handle it but otherwise... Metal

 

Beyond my little hobby level printer. Sent me to the web to look it up. Next up. Plan B with flattened bottle caps.

 

Looking forward to seeing this.

 

ACE hardware and look at washer selection?

 

Look up the Youtube videos on doing "lost PLA" sand casting.

 

For all the suggestions and sources. Right now, I’m using baby food jar caps, one secured with some kind of spacer I found, the others to be held by speednuts. I don’t trust the studs not to come off with a regular nut.
