Many 3D printers have their biggest axis at 250mm max (at least those of my friends that I asked). While you can rotate the print a bit to max out the space, you have to print pretty high which apparently can become unreliable.

I wonder if cutting 2mm on each side for 10" mountable pieces is fine. The mount holes are are 236,5mm apart (measured from the center of each). If they get printed with 8mm diameter, that’s 244,5mm (+4mm each side), so there’s only 3mm left on each side when reducing the total with to 250 (instead of 5mm at 254mm total). That seems pretty narrow but then that part is not the load bearing one. Any experience with this?
