It’s amazing how much our views change with time. My dad was definitely a super early adopter of cable when it became available in our area, if I recall it was 16 Mbps which was unreal to me in 2002. I made do with 5 Mbps in uni and it was totally usable.
But now, I’ve had 1Gbps for years and wow it’s so different, changes your habits too. I don’t hoard installed games as much, I can pull them down in minutes so why keep something installed if I’m not going to use it?
Red loctite on fastners that small has a recipe for being a bad time if it sets up proprly, I find some of the small screws around the hotend can already be prone to stripping due to things like plastic buildup thats hard to remove.
At least on the dragon, theres a sizeable gap between the inner and outer portions of the heatbreak and some distance between the block and the heatbreak, I’d be surprised if the threads get hot enough to worry about even without the hotend fan.
