For my son's "Historical Halloween" annual school event (this year's theme was Europe), my son chose to be Odin, the father of the Norse gods. This is one of his costume props, safe for school, with no sharp points or edges.
Most people know about Thor's hammer "Mjolnir", but not as many know that his father Odin has a spear "Gungnir". Some traditional accounts say that Gungnir never misses its target, even if it must pass through solid objects. And, just like Thor's hammer, Gungnir always returns to its wielder.
This spear blade is designed to screw onto a standard broom handle. The blade design is patterned after a real metal-blade design by The Viking Woodsmith. Historical records say that runes were carved on the blade, but the records don't say what the runes were. The runes on this spear spell "Gungnir" in Futhark.
The OpenSCAD script Odin_spear.scad requires scripts from two of my other Things: geodesic_hemisphere.scad from Geodesic hemisphere with regular polygon equator and circlestack_thread3.scad from Nuts&bolt baby dexterity toy. All the necessary .scad files are included in this Thing.
Printer Brand: Prusa
Printer: I3 MK3S
Supports: No
Resolution: 0.20 mm layers
Infill: 20% cubic
Filament: Prusament PLA Silver-gray
Notes:
All parts are included in one STL file. If you need to print one part, use your slicer to split it into separate objects and print only what you need.
The blade halves are 240mm long, designed to fit on the build plate of a Prusa i3 MK3S printer, which is 250mm wide, with enough room for a 4mm brim to prevent the parts from warping away from the build plate.
If your build plate is smaller, and a blade would fit diagonally on your build plate, then split the STL into separate objects in your slicer, delete all objects except one blade half, and print one blade half at a time, oriented diagonally.
Designed completely in OpenSCAD, unlike my son's previous spear wielded by Hawaiian King Kamehameha I, which was done in Tinkercad. I am particularly pleased with the ogive curves I made for the leading edge of Odin's spear.
