Tauon

I'm deviating a little from Alexanders box packing puzzles this month to bring you Tauon, an earlier design of his. Using only linear moves, are you able to remove and insert the 3 pieces into the frame? The frame is made from Avodire and Curatinga Rosewood with pieces and obstructions made from Red Grandis.  Designer: Alexander Magyarics Size: Approx. 2.75" x 2.75" x 2.75" Ships assembled, Moves: 21.2.3  (No rotations)
