My new all metal hottip from +TrinityLabs.
Reminds a bit if IKEA parts 
Let us know how it performs.
Initial report is not great. I can’t get it over 169C, and it takes longer than the heated bed (std Prusa) to heat up.
One good thing is that you can pull the filament right outta this thing whether hot or cold.
I have an email into TrinityLabs asking for help. We’ll see what they come back with.
Looks like a heating cartridge? Maybe the thermistor is reading wrong? I assume you did an auto tune on it ya?
I emailed TrinityLabs, who quickly responded with the fix. They shipped me a 24V resistor, so they’re reshipping the correct 12V one.
