I'm offering up my 3cm 'Alumide' (special material which was available only for a short time, made by infusing aluminum bits into the 3D printing process) Peanut puzzle...this is a spherical version of Stewart Coffin's 'Peanut' design #67 modified by George. The puzzle looks quite nice and is a lot of fun to play with! Pictures show just a small sample of the many different solutions possible with these six pieces!
