Hi Shapeways fans, Oskar's Matchboxes has become a classic do-it-yourself puzzle. Glue the matchbox drawers to five matchbox sleeves, and then try to close all matchboxes. This is the first Oskar puzzle that got wide publicity, starting with publication in a Dutch newspaper in 1983, and subsequently in many do-it-yourself books. Nowadays with 3D-printers, you can also 3D-print the puzzle yourself. Glue is needed to glue the parts together. My glue of choice is is transparent two-component epoxy glue (Bison Kombi). Watch the YouTube video. Buy the puzzle at my Shapeways Shop. Read more at the Non-Twisty Puzzles Forum. Check out the photos below. Enjoy! Oskar
