In addition, there are various super-portable lightweight irons on the market such as the '''[https://pine64.com/product/pinecil-smart-mini-portable-soldering-iron/ Pinecil]''', and various TS100 or TS101 models. These run on DC power from any source you can tap, such as your car, larger robot battery packs, and even a '''[https://en.wikipedia.org/wiki/USB_hardware#USB_Power_Delivery USB PD]''' charger or power bank.

	While you could get by with a pair of scissors to cut wires and a sharp knife to strip off insulation, it can be difficult to strip the insulation without damaging the underlying wire. A proper wire stripper will make this job easier. A pliers-style wire stripper (as shown) is quick and convenient; choose one that can handle the sizes of wire you are using.

	Nearly all bots use some fasteners to hold things together. Hex key or Allen key fasteners are the most popular since the fastener heads aren't as susceptible to damage as Phillips head fasteners. These come in many different styles and lengths for different uses. If your bot design requires you to remove a lot of fasteners to access the internals, consider getting a set that can attach to an electric drill or screwdriver.

	===Drills===
			==Drills==
	Electric drills are needed to make holes, to prepare material to be tapped (threaded for fasteners), and can also be used to quickly take your bot apart and put it together while making repairs and changes during an event. The quality and price of drills cover a huge range. Cheap drills are fine if you are only drilling aluminum or plastic, but they don't tend to last as long. If you are going to be drilling into steel or titanium you should get a higher quality drill from a brand name company. Consider getting a spare battery so that you won't run out of power during an event. While drills can be used to insert or remove fasteners from your bot, a large drill can be awkward to use with tiny robots; consider getting an electric screwdriver instead.

Squeeze-action 'automatic' wire strippers tend to work better for larger wires.		While you could get by with a pair of scissors to cut wires and a sharp knife to strip off insulation, it can be difficult to strip the insulation without damaging the underlying wire. A proper wire stripper will make this job easier. A pliers-style wire stripper (as shown) is quick and convenient; choose one that can handle the sizes of wire you are using.

			Squeeze-action 'automatic' wire strippers tend to work better for larger wires. These have a tension adjustment, and they will nick or break wires if the tension is set too high.

	Nearly all bots use some fasteners to hold things together. Hex key or Allen key fasteners are the most popular since the fastener heads aren't as susceptible to damage as Phillips head fasteners. These come in many different styles and lengths for different uses. If your bot design requires you to remove a lot of fasteners to access the internals, consider getting a set that can attach to an electric drill or screwdriver.

	A 3D printer, which produces plastic parts under computer control, can be a helpful tool. There are dozens of robot designs on [https://www.thingiverse.com/ Thingiverse] which you can download and print; typically these will include several parts that are assembled to become the body of the robot, and many have instructions and buying suggestions for finishing the working parts. Once you've got a bot design working to your satisfaction, you can print a supply of replacement plastic parts, which can be used for repairs after your bot becomes damaged.

	3D printing is especially useful for the smaller insect-class bots, where weight is a severe limitation to design. ~~Not all printable plastics are alike~~, ~~though~~. ~~The list below proceeds roughly~~ from ~~weakest to strongest~~.		3D printing is especially useful for the smaller insect-class bots, where weight is a severe limitation to design. However, even Heavyweight-class builders use 3D printing to make composite reinforced components, custom compartment insulators, and wire guides. Keeping electrical parts and cables away from metal plates reduces the risk of damage and short circuits.

	*PLA is inexpensive, but brittle.[https://www.youtube.com/watch?v=cIH-HS-SScY] It is the most common 3D printing filament. It rarely warps in use and is great for tiny parts.[https://shop.prusa3d.com/fotky/PLA_TechSheet_ENG.pdf] It's a great starter material, and recommended for printing prototype parts. Many builders prefer other plastics, especially for their active weapons or armor.		====3D printer materials====
	*PLA+, a modified PLA with additives, may be stronger. With an acrylic component, for instance, it may show much better impact resistance.[https://www.youtube.com/watch?v=uAoZCpXoPWo] Inland and eSun claim their PLA+ products are 10x stronger than regular PLA.		The list of common 3D printable plastics below proceeds roughly from weakest to strongest.
	*PETG (a copolyester) is more heat resistant, more flexible, and less brittle than PLA.[https://www.youtube.com/watch?v=uAoZCpXoPWo] It is well suited for 3D printing mechanical parts. It is more likely to flex under impact.
	*ABS is a strong and reasonably impact-resistant material at a moderate price, but warps easily and smells worse while printing. You'll probably need to print it in an enclosure for best results.		*'''PLA''' is inexpensive, but brittle.[https://www.youtube.com/watch?v=cIH-HS-SScY] It is the most common 3D printing filament. It rarely warps in use and is great for tiny parts.[https://shop.prusa3d.com/fotky/PLA_TechSheet_ENG.pdf] It's a great starter material, and recommended for printing prototype parts. Many builders prefer other plastics, especially for their active weapons or armor. Pure PLA is made from cornstarch[https://all3dp.com/2/what-is-pla-plastic-material-properties/] and gives off a corn syrup odor which reminds some people of waffles.
	*Nylon is tough and flexible. Regular nylon is hygroscopic and ~~should~~ be kept in dry storage; consider buying a hybrid nylon material that doesn't absorb water as easily.		*'''PLA+''', a modified PLA with additives, may be stronger. With an acrylic component, for instance, it may show much better impact resistance.[https://www.youtube.com/watch?v=uAoZCpXoPWo] Inland and eSun claim their PLA+ products are 10x stronger than regular PLA.
	*Polycarbonate is super strong - your robot arena walls are probably made from it! Many printers can't print it, though, because it must be heated to an extreme temperature.		*'''PETG''' (a copolyester) is more heat resistant, more flexible, and less brittle than PLA.[https://www.youtube.com/watch?v=uAoZCpXoPWo] It is well suited for 3D printing mechanical parts. Since it is more likely to flex under impact its resilience may be useful to the bot builder, but it is 2-3% heavier than PLA. Observe manufacturer's recommendations when printing, as it tends to stick very strongly to smooth print beds. You'll notice a fairly mild hot-plastic odor when printing.
	*Carbon-fiber reinforced materials are extremely tough, and ideal for combat robotics. These are usually polycarbonate or nylon with chopped fibers embedded inside. You should strongly consider using these when plastic parts are needed for beetleweight designs.[https://www.youtube.com/watch?v=g9hUcqsNJco] This material requires a durable printing nozzle, as the carbon-fiber strands or particles are highly abrasive.		*'''ABS''' is a strong and reasonably impact-resistant material at a moderate price, but warps easily and smells worse while printing. Its low density makes it one of the lightest of all printable plastics (PLA is about 20% heavier for the exact same print). You'll probably need to print it in an enclosure for best results; this keeps its temperature even during printing, so that it only shrinks after printing instead of warping. Many hobbyists ventilate the enclosure to the outdoors with fan(s) due to the odor.
			*'''Nylon''' is tough and flexible. Regular nylon is hygroscopic and must be kept in dry storage; consider buying a hybrid nylon material that doesn't absorb water as easily.
			*'''Polycarbonate''' is super strong - your robot arena walls are probably made from it! Many printers can't print it, though, because it must be heated to an extreme temperature (about 275°C or 525°F).
