Free content
On this website you will find free calculators, guides, tables, templates and 3D generators. I create them with care. However, I give no guarantee that they are correct and complete or that they suit your individual case.
This content does not replace legal, tax or other professional advice. If a lot depends on it for you, please ask a professional, for example a lawyer, a tax adviser or a specialist company.
Printed parts
The 3D generators create files for your own printer. You print and mount the parts at your own responsibility. Check every printed part yourself before you use it or put weight on it.
Do not hang anything in a place where it hangs over people, for example over beds, seats or walkways. A part from your own printer can break, even if it held before.
Liability
For the free content, I am only liable for intent and gross negligence. For injury to life, body or health and for claims under the German Product Liability Act (Produkthaftungsgesetz), the statutory provisions apply.
