My 3d printed gjallarhorn. Was done on a TAZ 5 with hatchbox PLA. Took about 2 rolls of PLA at 12 percent infill. Took me about 2 and 1/2 weeks to print everything and quite a bit longer to sand and paint. As i stated in the comments section of this post if you live in the USA and want to make this then you need 3 inch and 3.5 inch PVC pipe. You then must print every part at 98% scale for the pipes to fit into the pipe connector and barrel sections. All of the parts fit together really well.
