Forget the endless pile of downloads that look great on screen but waste your time and filament on the printer. Big Macks 3D makes practical, tested models designed to fit your printer, your needs, and the way you actually use them.
🖨 First, tell us your printer. Every model is generated to fit its build plate — pick it once and it follows you around the site. Pick your printer
Made to order
Choose a model, set the dimensions and options, and use the live preview to make sure it’s what you have in mind. Your printer’s build volume is already part of the equation.
Your specifications are used to generate the actual parts you’ll need. We size and split them to fit your printer’s build volume, so you don’t have to remix, rescale, or guess whether everything will fit.
Want to print it yourself? Download the print-ready files and send them to your slicer. Don't want to spend hours printing and assembling it? Choose print & ship, and we’ll print it for you and send the finished product to your door.

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 is sized to the printer doing the printing, and the logo and engraved sizes come as color inlays only where you can print them. The one at the top is the one new configurations start on — pick any row to make it that.
Adding one is the same picker: choose it in My Printer, or add one we don’t list yet.
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.
