About build materials, tape and sleeving

Raw materials and consumables for building and finishing projects. 3K carbon fibre plates, sheets and square tubes make light, stiff frames for drones and robots, and FR4 copper clad laminate is the starting point for circuit boards you etch or mill yourself. Kapton polyimide tape masks and insulates parts that get hot, adhesive-lined 3:1 heat shrink seals splices, and expandable braided sleeving and PTFE tubing protect cable runs.

There are also resealable anti-static shielding bags for storing boards, nylon zip ties and reusable hook-and-loop cable ties, wet and dry sandpaper from 120 to 3000 grit for finishing 3D prints, hot-melt glue sticks and high-speed steel rod. Carbon fibre dust irritates skin and lungs, so cut and sand it wet or wear a dust mask, and remember that carbon fibre conducts electricity.

Questions about build materials, tape and sleeving

Can I make circuit boards from the copper clad laminate?
Yes. FR4 copper clad board can be etched with a printed mask or milled on a CNC router with carbide PCB bits, which are in Tools. Double-sided board lets you route traces on both faces.
What's the difference between 2:1 and 3:1 heat shrink?
The ratio is how far the tube shrinks: 3:1 tubing shrinks to a third of its supplied diameter, so it fits over larger connectors and still grips the wire. Adhesive-lined tubing also seals the joint against moisture.
How long does delivery take, and what does shipping cost?
Most parts ship to Canadian addresses directly from our supplier partners, most of them outside Canada, and most orders arrive within 1 to 3 weeks; the product page shows its own estimate. Items marked eligible on their product page ship free once the eligible items in your cart total $20 or more (a cart of many low-priced parts needs more than $20 of them, and the cart shows how much). Until then, and for items that aren't eligible, each item pays its supplier's shipping quote for your address, and checkout shows every charge and the tax before you pay.
