This model is intended to fit Prusa beds that are non-standard, usually the ones that come in clone kits. They are longer, however they still work as normal with most Drylins/LM8UUs.
I printed and designed this with ABS so tolerances may vary if you decide to go with a different filament. I can't imagine it would have much effect on this model.
