What you are buying
Wheels you designed yourself, printed to order in resin. Nothing is made in advance and nothing is held in stock — each order is printed for you after you place it.
MackBricks is an independent maker. We are not affiliated with, endorsed by, sponsored by, or connected to the LEGO Group, and no LEGO® product is supplied with an order. Where we describe a part as fitting a particular system, that describes fit and nothing else.
The price
The price shown as you design is the price you pay. It is recalculated on our side from the exact part you ordered before payment is taken, so the figure on the checkout page is the figure you were quoted.
Cancelling
You can cancel and be refunded in full at any point before we start printing, from your Orders page. Once printing has begun the resin is committed and the button disappears — get in touch and we will do what we reasonably can.
If a print fails
Printing fails sometimes. If yours does, we reprint it at our cost. If we cannot make it work, we refund you in full.
What we cannot promise
These are printed parts, not injection-molded ones. They are dimensionally accurate and test-fitted, but resin is more brittle than ABS and a printed wheel will not behave identically to a molded one under load. Buy accordingly.
Your designs
Your design stays yours. We use it to make and support your order and for nothing else. We may print the same or similar wheels for other customers — the palette is shared and the sizes are standard, so identical designs will occur naturally.
