It would be a good candidate for casting. The original was investment cast I think but I don't want to go down that rabbit hole this timeCast it!

You could get them 3D printed in metal...may not be as expensive as you think....or CNC'd...PCBway and JLCPCB should be able to provide online quotesIt would be a good candidate for casting. The original was investment cast I think but I don't want to go down that rabbit hole this time
Ref my thread on humidity, I was having mixed results with PETG but realised that my (generic) "SunLu" enclosure was lying in the other room, which kinda defeats the purpose.
So I've restarted a failed print with the printer inside the enclosure and put the Sonoff temp & humidity sensor inside the enclosure:

Seems these enclosures work!
Now if I can just get one big enough to wrap my garage...
However the issue with PETG, is that it absorbs moisture, and it's that moisture that causes print quality issues, as it steams off as it goes through the hotend causing inconsistent extrusion.
I wonder how many laser users we now have on here.Some of my own designs today. I am building an enclosure for the laser.
A couple of handles, signs of warning and one of eight corners for the 20 x 20 extrusion.

I bought mine 2 years ago but never really used it. It is a 15w diode so doubtful it will cut much.I wonder how many laser users we now have on here.
I just purchased another one but can't get it to cut over 8mm.
The one I purchased should cut 20mm but I cant find out whats wrong with it.I bought mine 2 years ago but never really used it. It is a 15w diode so doubtful it will cut much.
I expect there are a lot out there as they are so cheap!
Yep.It's a hobby in itself, isn't it?
Not today, but yesterday and the day before ...

Experimenting with PETG (black) and ASA (Red).
I got a part out of the PETG relatively easily. Looks OK, but not very neat

The ASA was more of a challenge which wasn't helped by height of the nozzle varying from print to print. Turns out there was a bug in the firmware so I needed to update that (which wiped out my previous flow calibrations - there's a severely under-extruded part in the pile of red scrap above). I also got a cheap 'tent' to put over the machine as I couldn't even print the flow-rate patches without it. But, with the printing speeds reduced to ~50% of the factory presets, the ASA actually prints OK.

Not sure if my 'pressure advance' needs tuning, or if it's still under extruded.

The bottom surface is still a bit rough, but I've since found the setting to increase the flow for the first layer. I think this one could be usable.

These PETG prints look like mine. I’ve found PLA to produce a far neater output.
