A rail to allow mounting of Multibin popins to a 2525 extruded rail. Uses M5 button head screws (10mm IIRC, will check). Prints well vertically with a brim on a CoreXY, might benefit from some supports under the corners (the rest prints fine without them).

Why? I use a VsionAir Independent Airbrush Station, which has 2525 extrusion. Being able to mount Multibins to it as tool or paint caddies is quite handy. Open to rejigging this for 2020 if needed.
