Timing belts are a fantastic way to transfer rotational motion (from a stepper motor) into linear motion (along a rail) and these GT2 belts are excellent for the task. They have a special profile with rounded teeth which reduces slippage. Often used for precision 3D printers and CNC machines. This belt is 1164mm long (582 teeth on a 2mm tooth pitch) and is 6mm wide. It comes in a loop but you can of course cut it down if you need a shorter...

Oh boy, now you have no excuse for not building that robot! Nothing is easier or faster than building with extrusion and we've added 20mm square aluminum extrusion and components to our catalog. This product is the extrusion itself. Made of aluminum, its exactly 20x20mm square and has slots on all four sides. You can use T-nuts that slide into the slots to connect plates, couplers, PCBs, cut-outs, etc. Its sort of like a big-sized Erector set....

If you have an 8mm linear rail, you'll want to give it a bit of guidance and support to help it through the day. Sometimes a good word and a pat on the back is all you need, but when that's not enough, use a pair of these aluminum cast rail supports! Usable with any 8mm linear guide, you can simply slide the rail through, then tighten the clamp screw at the top to fix it in place. Then use up to 6mm diameter bolts to attach them. If you need to...

Connect this to that with a set-screw coupler. These couplers are made of machined aluminum and have a spiral cut that makes them slightly flexible so they can be fit to two shafts even if they are not perfectly co-linear and will help reduce binding effects. The way they're cut, they're a little springy in the X Y & Z linear axis but not in the rotational axis. That means that you won't get increased backlash - so they're suitable for precision...

This linear ball bearing is sort of the opposite of the radial ball bearings you may be familiar with. Its intended to slide along an 8mm linear shaft, rather than rotate around it. These are very slim, and good for when you want to attach a motion carriage onto a railing without adding a lot of weight. These are very basic bearings, they're meant for a stepper-motion controlled setup so they're not ultra-smooth. They're best used for DIY/hobby...

Cute as a button, these button-head hex screws are what we suggest for putting together a project with our slotted extruded aluminum. Use a 2.5mm hex wrench to attach/detach. This length is good for attaching something about 4mm/0.15" thick to 20x20 extrusion. Comes in a pack of 50. M4-20 threads, 10mm threaded body. Button Hex Machine Screw - M4 thread - 10mm long - pack of 50 (6:35)

This is an interesting hardware piece addition for 20x20 aluminum extrusion. Rather than being a 90 degree type plate, its a hinged piece that connects the end of one extrusion to the side of another, but with any angle you wish. You can loosen/tighten the angle with the screw on the side. Given its just a bolt, it's not incredibly strong so while you can use it for structure, its not a load-bearing connector: make sure there isn't a lot of...
