It will be a 240x280x70ish speaker stand. The first go ground with it flat and support free resulted in warping despite a 60°C chamber, so I stood it on its end, cut print speed by a third, and added the breaks to reduce stress.
This will take a while…
Note that the bottom has a chmafer, so although there’s a shadow it’s not warping.
No, magsheets didn’t exist back then, we used mostly glass beds coated with hairspray, kapton tape or whatever we thought would work at the time… the clips were to hold the glass to the heatbed (usually a pcb heater).
Ah, that’s true. I guess they carried over into the early spring steel era.
Related: clips are a much better option than using double sided tape to attach glass to your bed. I just pulled my wanhao i3 clone out of retirement for my kids to mess with and getting the beat up ultrabase bed off was lots of fun…
