About this item

  • Complete 420 Piece M3 Kit: Build, repair, and upgrade 3D-printed parts with one organized set. Includes 120 brass heat-set inserts, 200 socket-head M3 screws, and 100 matching M3 nuts, plus a 60W digital soldering iron, 2 dedicated M3 insertion tips, 2 connecting rods, 2 hex keys, and a compartment storage case. Components stay separated by size for faster selection during assembly and maintenance
  • 10 Screw Lengths 3 Insert Sizes: Match hardware to different wall thicknesses, joint depths, and assembly needs. The kit includes M3 screws in 6, 8, 10, 12, 16, 18, 20, 25, 30, and 40 mm lengths, with 20 pieces of each size. It also includes three brass heat-set insert sizes—M3×4×5, M3×5×4, and M3×6×4—with 40 pieces of each size, giving you flexible options for prototypes, housings, brackets, and DIY builds
  • 60W Digital Temperature Control: Adjust the soldering iron from 200–500°C / 392–932°F and switch between °C and °F display modes. The clear digital screen helps you monitor temperature while working with different thermoplastics, insert sizes, wall thicknesses, and installation depths. Choose the heat setting based on the material’s temperature tolerance, and test on scrap material first before installing inserts in the finished part
  • Dedicated M3 Heat-Set Installation: Two M3 insertion tips and two connecting rods help transfer heat to the brass insert while supporting straighter placement. Select the matching insert, mount the M3 tip, heat the insert, hold the tool perpendicular to the printed part, and apply light downward pressure until the insert reaches the required depth. Remove the tool vertically and allow the plastic to cool before threading in the screw
  • For 3D-Printed Assemblies & Repairs: Add reusable M3 threaded connection points to compatible thermoplastic parts such as enclosures, brackets, jigs, fixtures, models, prototypes, and DIY components. The organized assortment makes it easier to replace hardware, revise designs, or service parts that are assembled repeatedly. Confirm pilot-hole diameter, insert depth, material temperature tolerance, and screw length before installation.

FAQ

What types of products does Stemora offer?


Stemora offers supplies for science experiments, microscopy, biology learning, measurement, laboratory organization, electronics, robotics, coding education, 3D printing, maker projects, and classroom activities. Available products and specifications may change over time.

Are Stemora products suitable for children?


Recommended ages vary by product. Please review the product description, manufacturer guidance, included warnings, and required skill level before purchasing. Products containing small parts, tools, electrical components, glass, or chemicals may not be suitable for young children.

Is adult supervision required?


Adult supervision is recommended for children and students, especially when using electrical components, sharp tools, heated equipment, glassware, small parts, or experiment materials. Customers are responsible for following all product instructions and safety precautions.

Can these products be used at home and in classrooms?


Many products may be suitable for classrooms, home learning, science projects, maker spaces, and hobby activities. Suitability depends on the specific product, learning environment, user experience, and intended activity.

How can I check what is included with a product?


Please review the product title, description, specifications, images, package quantity, and included-components section before ordering. Items shown for demonstration or scale in product images may not always be included.

How do I know whether an electronic or robotics part is compatible?


Check the listed dimensions, voltage, connector type, board compatibility, operating requirements, and supported platforms. Compatibility is not guaranteed unless it is specifically stated on the product page. Contact us before ordering if you need clarification.

When will I receive tracking information?


Tracking information is generally provided within 3–5 business days after an order is confirmed. In some cases, processing may take approximately 7–8 business days. Delivery may require an additional 4–5 business days after tracking becomes available, depending on the carrier and destination.

Why did my order arrive in separate packages?


Products in the same order may be shipped from different fulfillment locations. As a result, items may arrive separately and have different tracking numbers. You will not be charged additional shipping fees solely because an order is divided into multiple packages.

Can I change or cancel my order?


Contact us as soon as possible at vaioamaonaoak@gmail.com. We will try to assist, but changes or cancellations cannot be guaranteed once an order has entered processing or has been shipped.

What should I do if an item arrives damaged, defective, or incorrect?


Contact us promptly at vaioamaonaoak@gmail.com with your order number, a description of the issue, and clear photographs of the item, packaging, and shipping label. Please retain the product and original packaging while we review your request. Eligibility and available resolutions are subject to our Return & Refund Policy.
