Made to order
Choose a model, set your dimensions, options and colors, and spin the live 3D preview until it’s exactly right.
Your specs run straight into clean, print-ready parts — plated to fit your printer’s bed.
Secure links hit your order page and inbox the moment they’re ready — good for 30 days and five downloads each.
We size every model to your printer, so we need to know how big it can print. It’ll be saved for the next person with the same machine.
These are the printable sizes — the biggest part your printer can actually make, the numbers your slicer shows as the build volume. Not the bed or the removable plate, which are usually a little bigger.
The build plate is the removable sheet you pop prints off; it’s usually a little bigger than the printable area. A plate rack is cut to the sheet, not the bed.
A printer stand is built around your printer’s feet. Give us all four and we can build you one — or skip them and add them later. Measure the BASE — the slab it stands on — not the machine’s widest point. Gantry legs, Z columns and X arms usually overhang the base and hold up nothing.
Every model on the site opens in these three. Primary is the largest surface, secondary the part that contrasts with it, and tertiary the accent — feet, trim, the parts that tie it together.
