Low Cost FlexPlate type System

My glass plate glued to a flexplate finally had a enough pieces ripped off that I could not use it. I saw an inexpensive flexplate like system and ordered it.

The inexpensive system is just two very large refrigerator magnet strips. One plate has a sticky surface for mounting and the other plate has a print surface.

I glued the sticky surface to the glass plate for flatness. The upper plate stuck to the lower plate well enough to work, but not as much as the Flexplate. The glass plate dings did not pass through to the top surface.

If I did not have a Flexplate installed I would glue the sticky to the plate, and glue a glass plate to the upper for flatness. I have this ordered in 12x12 for my large printer and will update when all of the parts come in.

This looks like a very inexpensive system that will function just as well as the flexplate.

The magnetic flexplate like surface did not hold as well as this:

I have not yet printed on it but I suspect it will have the same flaw as the flexplate system and large parts will curl on the bottom by pulling the print surface up. I got around that by glueing glass to the top surface. This works very well for the flexplate system.
