Conventions
¢ Casting: Side walls of the wall thickness, an inside fillet, key width and length and, on the slot 10 and 45 brackets, a curved diagonal: illustrative, not any maker's design.
« Mark: The CommunityCAD mark recessed 0.3 mm in an outside side wall. Illustrative.
« Values: No published standard: every maker casts its own bracket, so each size is the reference maker's own casting (Misumi, OpenBuilds, item), single source. item's sheets give only the outline and holes: its wall and key are house proportions, its hole ISO 273 medium for M8. On the 20 B-type slot 6 double, Misumi's drawing alone shows which holes sit on its rows. The two readings disagreed, and the owner accepted this layout: 4 holes on the first leg in two rows, 2 on the upright in one, no centre column.
« V-slot holes: OpenBuilds' drawing gives the holes of the 20 V-slot bracket no position, so they sit at the middle of the leg and of the width, a rule rather than a maker's dimension.
¢ Finish: Cast aluminium, the reference part's finish: render and metadata only. First leg's profile face at Z = 0, the upright's at X = 0, the keys beyond them.
