s0 Is Not A SysadminFifth time lucky with modelling this replacement collar to hold the clear viewing window onto a vintage coffee kettle.
The thread was an odd square-ish profile with much less trapezoidal draft than the standards I’m familiar with, so I modelled it manually in Fusion 360 with the helix function. It’s a bit annoying that you can’t directly helix a profile, but have to create a square/round one and then sweep the profile along that.
Now I will be asking a favour from friends with SLA resin printers to reproduce it in something a bit less thermoplastic, since it’s for a kettle!
