Norsaq

prusaprinters

This is a norsaq I modeled from plans on a now-defunct geocities site, with some small liberties taken with the rounding and the finger indentations to my taste.  This is intended to be a functional norsaq, not just a model, although I don't have the skill to test it myself just right (if you print and use one successfully, I'd love to hear from you).  To that end I've provided files for printing in both a single piece (which will require a pretty large printer, as it's over 400mm tall) or in two pieces which should fit on most average sized desktop 3D printers.  As a bonus, the split-in-half design gives you two nice flat surfaces to put on your print bed.I printed mine in glass filled ABS filament, which proved exceptionally strong and also does a good job of resisting warping off the print bed.  I used 5 walls, 15% gyroid infill, and added a 3mm bottom layer in case I needed to file it down to get the mating surfaces flat, which I ultimately decided against.I've included both STEP and STL files.  If your slicer supports them, the STEP files are both smaller and more accurate for these curved parts.  The original FCstd is also included if you want to modify it.The top and bottom parts are designed to be epoxied together with ¼" dowels.  The holes are modeled true to size, but will probably print a little bit undersized.  You can use a ¼" drill bit to get them perfectly sized, just make sure to run your drill slowly.  If you drill them out too fast the heat buildup will soften the plastic, and you want the plastic guiding your drill bit rather than the other way around.  After that you can just coat your dowels in epoxy (maybe lightly plane one or two flats to give the epoxy some room to squeeze out), add some to the mating surfaces, and squeeze them together to cure.  I also use a ½" drill bit to clean out the harpoon hole, just pushing it through and turning it by hand.
