This new puzzle was published on Puzzle Will Be Played earlier this year. Six identical pieces can be combined using a sequence of 9 steps to make the... traditional burr puzzle shape.
Initially, I overlooked this as a non-printable puzzle but yesterday I noticed that if the pieces are rotated vertically they should print perfectly well.
Copyright for this design belongs to Logan Kleinwaks so non-commercial copies only please.
If you are interested in a more challenging variant of this puzzle, Logan has just published Lynxes of Spain and Lynxes of Portugal which also look printable and reuse some of these pieces in combination with some new ones.
Update 21/03/2019
To make Six Iberian Lynxes puzzle, print 6 of Lynx_8_04_01_S1.
To make Lynxes Of Spain puzzle, print 4 of Lynx_8_04_01_S1 and one each of Lynx_8_04_01_S2 and Lynx_8_04_01_S3.
The digital model was made in Burr Tools and the STL file was then exported with the following settings: Cube size - 8 mm Bevel size - 0.4 mm Toleranc...e - 0.1 mm I printed 6 copies in ABS on a Mendel90 printer at 0.2 mm layer height, 0.49 mm extrusion width, 30% hexagonal fill, 2 perimeters, four solid layers top and bottom, speed 30 mm/s.
