Fully Parametric 90 Degree Adjustable/Sliding Bracket/Fence - PROTOTYPE

Are you a DIYer who does wood working, makes tool jigs, or wants a completely parametric "head start" to help you to make custom right-angle motor mounts?

Do you ever make projects that require a 90 degree bracket or adjustable fence/reference edge? (for example: soap cutter, wood router fence, DIY table saw fence, vice/clamping surface, etc)
