FAQs
Where are the products shipped from?
STEM kits, boards and tools ship from our fulfilment partner’s warehouse in China with tracked shipping. QIDI 3D printers and accessories ship from QIDI’s EU warehouse. If you order both, they arrive in separate parcels. See our Shipping Policy for the full list of countries.
How much is shipping?
Nothing: shipping is free on every order, to every country we ship to, whatever the order total. That includes QIDI 3D printers.
How long does it take to receive my order?
Kits: orders are processed within 1–3 business days, and delivery usually takes 5–10 business days after dispatch. 3D printers: 2–5 business days within the EU; 7–14 business days elsewhere. If there’s a delay, we’ll let you know in advance so you can decide whether to wait or cancel for a full refund.
Will I pay customs or import fees?
No. Our prices include VAT, and we ship DDP (Delivery Duty Paid) to the countries where it’s available at checkout, so we handle customs and pay import duties for you. If a carrier ever asks you for charges on a DDP order, don’t pay. Contact us and we’ll sort it out.
Do the kits come with tutorials?
Yes. Every STEM kit comes with free step-by-step lessons in our Learning & Projects Hub, with code and wiring diagrams.
Do I need programming experience?
No. Our beginner lessons start from the basics, like blinking your first LED, and build up step by step. Each kit’s page and lessons show the difficulty level.
Are the kits suitable for children?
Many kits are designed for learners aged 8 and up; check the age range on each product page. Children should build with an adult, especially when using tools or power supplies.
Can I return a product?
Yes. You can cancel within 14 days of delivery without giving a reason, and we refund you within 14 days of your cancellation. See our Refund Policy for details.
What happens if I didn’t receive my order?
If your order doesn’t arrive because of a shipping issue, we’ll send a replacement or issue a full refund to your original payment method.
Can I share my own project?
Yes, we’d love to see it. Sign in and submit your project. Our team reviews every submission and publishes the best ones in the hub, credited to you.
