Printable Interlocking Puzzle Remix

thingiverse

I'm designing an interlocking puzzle based on a design found on thingiverse.com, specifically item #31639. This project serves as an excellent example for my students to hone their skills in mathematically sketching three-dimensional objects. The produced item is constructed using rods with a length of 10 millimeters and an allowed deviation of 0.2 millimeters, ensuring that it fits loosely and providing room for adjustments. By decreasing the tolerance, one can make it fit more precisely, reducing it to as little as 0.16 millimeters if desired. I'm considering scaling up the size of the puzzle to accommodate larger pieces. To create this interlocking puzzle, I utilized OpenSCAD, specifically version 2014.11.25, allowing for precision modeling and complex design capabilities. In an update, it's now possible to convert any file from xmpuzzle format, which is commonly used by Burrtools, directly into OpenSCAD using the accompanying code 'xmpuzzle.scad'. This enhancement simplifies the process of generating designs. Following a further review, I found that the conversion script contained one critical line of code missing; it has been now included in its corrected version. Here are some guidelines for assembling this puzzle: I've printed this object using 1.75mm PLA with my Kossel Mini 3D printer equipped with Marlin running on a RAMPS 1.4. To do so, I used the following parameters: - Layer height: 0.25 millimeters - Two consecutive layers were allowed - A low infill density of 10% The printing speed was maintained at 45mm/s except for perimeter regions where it was reduced to 30mm/s. Printing took place in an environment with a temperature setting for the extruder at 200°C and no heating bed.
