Standard Components¶
(need renderings or images for shoulder screws, servos, bearings, etc.)
The laser-cuttable parts of the flat-pack kit are designed to be used with particular standard fasteners and components. The kit itself is designed on a metric grid. But this being the USA, both metric and inch-sized component systems are supported to varying degrees, simply because inch-sized 1/4-20 fasteners are often more readily available than metric M6 fasteners.
