Modified version of Mr. Coffin's puzzle with reduced radius sticks.
This avoids the problem he notes in: AP-ART A Compendium of Geometric Puzzles by Stewart Coffin 2018: "Notice that each stick intersects with five others and must be notched accordingly. It turns out those notches are so deep that they would likely cut the sticks into pieces."
With inspiration from my construction of the puzzle on: http://www.2ndlook.nl/3dpuzzles/puzzles/sirius/engdescription.htm
