Curved Wedge Rail Hold Down

An additional idea for securing minis via the rail system of non-standard sizes could be curved wedge hold downs. Making use of the wedge shape from some of the angled nuts, the curve could be inverted to wrap around the edge of a mini in about roughly a 1/4 circle shape or less. With, in my case, 28.5mm bases, they're just wide enough that they don't allow for easily sandwiching the mini between two hold downs -- normally, from what I've seen, one of the 15mm hold downs is needed at least. This could potentially free up more of the rails for use by removing the need to use a 15mm hold down, since even with a base of such size partially blocking one of the rail slots, a wedge hold down could simply be slotted against the outer edge of the base. Said wedge could likely be further secured by the existing screw post system.
