We answer everything that arrives, though sometimes it takes a few days. To make the answer useful, tell us:
- If it's a calculation error: the numbers you entered and the result you expected.
- If a printer is missing: the exact model and, if you've measured it, its average power draw.
- If it's an idea: what you'd like to calculate, and what for.
What we can't do
- We don't give tax or accounting advice: the prices these tools calculate are before tax.
- We don't take 3D printing commissions and we don't put people in touch with workshops.
- We don't store your calculations, so we can't recover them for you: use the «Copy link to this calculation» button to keep them yourself.
