Oh I thought via SD was better as you dont have to worry about random disconnects.

But also wont the PLA melt or warp slightly if you use it to make these bed extenders?

I used a SD card only once, to see if it worked,
and have been using USB ever since, It works great for us.
(Much easier to send Slicer files thru USB, with no need to change file types)

No, We never get the bed-temp above 100C, usually at about 80C max on top of glass, and they will not melt at that temp.
I don't think the extenders ever get to that temp though.
(Have not seen any warping of bed-extenders either)

Since the glass is mainly held in place by the hair-spray
all the extenders do is keep it positioned while spray is drying
and to keep fingers away from sharp glass corners.
