// Module: manfrotto_rc2_plate()
// Synopsis: Creates a Manfrotto RC2 tripod quick release mount plate.
// SynTags: Geom
// Topics: Parts
// See Also: threaded_rod()
// Usage:
// manfrotto_rc2_plate([chamfer],[anchor],[orient],[spin]) [ATTACHMENTS];
// Description:
// Creates a Manfrotto RC2 quick release mount plate to mount to a tripod. The chamfer argument
// lets you control whether the model edges are chamfered. By default all edges are chamfered,
// but you can set it to "bot" to chamfer only the bottom, so that connections to a model larger
// than the plate doin't have a V-groove at the junction. The plate is 10.5 mm thick.
// Arguments:
// chamfer = "none" for no chamfer, "all" for full chamfering, and "bot" or "bottom" for bottom chamfering. Default: "all".
// Examples:
// manfrotto_rc2_plate();
// manfrotto_rc2_plate("bot");
