FLSUN Q5: 200 mm. QQ-S and SR: about 260 mm. V400: 300 mm. Enter a custom diameter for other beds, such as 370 mm for the Anycubic Predator. Check your printer's mount positions.
A top-down DXF of your bed: the outer shape becomes the plate, and round holes in it become printer mounts (by size) or 3 mm dowel holes. Anything else in the file is ignored.
Enter the print area your printer lists. The plate is made larger on each side so an oversized flex sheet can overhang the print area and lock into dowel pins: a 500 × 500 print area gets a 505 × 505 plate.
Positions from the centre of the print area, mm. The hole you are editing lights up on the drawing.
ø3 × 20 mm at mid-thickness. A second bore goes in the opposite edge.
Dowel pins are unsupported on round plates: the circular flex sheet cannot use the straight-edge stop rule.
ø3 dowels, 6 mm into the print surface, placed so the flex sheet's edge lands on them. Pins may sit beyond the print area; the plate grows to keep 4.5 mm of aluminium around each one.
The sheet sits with its back edge against the dowels, centred on them, and its tab hangs over the front edge. Upload the DXF of a sheet you already own to check that it lands on the dowels and covers the print area.
M3, tapped into the underside of the plate and cleared through the pad and backer. Positions from the centre of the print area, mm.
Every custom plate gets a look from us before it is quoted. Send the configuration and we email you a quotation with a payment link, usually within two business days. Nothing is charged now. Lead time is 6 to 8 weeks after payment to start and will fall to 3 to 4 weeks (a custom heater pad is what sets it); shipping is included.

This is the exact JSON the generator turns into a verified SolidWorks plate, heater pad and backer.
