That is really awesome!
I took that .scad file and started playing around with it.
Would it help anyone to print temporary plates as modules? Like this:
(Flippable, just print as many as you need) for a 1400MM span, just print 7 identical parts, then when you can cut the final plates just swap them all out…
Not nearly as elegant as what @vicious1 designed for the temporary plate- but it could allow you to make a full span set without too much effort on a printer.
The code is ugly as can be because I’m still wrapping my head around what @jamiek did here… but:
Doesn’t look like I can attach a .3mf or a .scad here in the forum. .scad is too ugly to share without me cleaning it up, but this would fit most 3D printers’ beds.
