Have you ever needed a spear to hunt grizzly bears? Well now you can make one for $2! ( DO NOT ATTEMPT TO HUNT GRIZZLY BEARS ) I bought a 10 ' section of 1/2" pvc for $1.80 at my local Home Depot and this spear head cost about 27 cents (depending on the cost of your filament). For some reason when i load my files i've made into repetier the scale is all messed up, So if this happens to you i scaled my part by 12-13 for a snug fit (glue you wish). 1) download and print the file (may need support and requires a fan for optimal printing. May also require a brim depending on your printer. I printed with 50% infil.) 2) Buy a 1/2" pvc pipe of any length desired, I made mine with a 4" pipe . 3) Insert the spear head base into the pvc pipe, sanding may be required. 4) Glue the spear head into the pipe (optional) i left mine friction fit, that way if the spear head were to break i could easily replace it. 5) Have fun impaling boxes or what ever else you would do with this. Be careful with this as it could hurt sombody, i am not responsible for injury, death, mauling via grizzly bear, or any other user/bystander accedents. HAVE FUN!!!
