Pyramidst packing puzzle

[UPDATE] After thorough testing, multiple solutions (three) of the original puzzle were found, so I have removed the old files and updated them with a new version that includes an additional small cone for a total of 11 pieces to be packed. The size of the box, lid and pieces is now 50% the original to make it easier, faster and cheaper to print (though more fidgety!). We are confident now that there is only one unique solution to the puzzle (excluding mirror solutions). Special thanks to KNOX from the Mechanical Puzzles Discord for finding the additional solutions and the new unique solution with the additional small cone.[/UPDATE] This is my new packing puzzle Pyramidst.The goal is to fit all 11 pieces inside the box and be able to close the lid comfortably (no force is required to solve the puzzle).I hope you enjoy it! If you are really struggling with finding the solution, message me and I can send you a picture of the solution.
