Is there any way I can get a file of all the pieces fully together? I can't seem to figure out how to merge them as one piece. I'm trying to print at 25% this size

Thank you for this thing! Thumbs up to you!

I rescaled the pins at 0.95/1.

I'm reading a lot of reviews of poor sturdiness. Might I suggest revising this thing so that a section of 5/16 all-thread is fed throughout all the parts, and somehow synched together.

The assembled sword is just under 2 feet. But you can add as many middle segments as you like, we've built it up to 4 feet before (though it gets a little top heavy)

Were supports used?

Don`t need them except on the hilt - print it flat with supports in the holes.

For the blades, I used 4-5 shells for it to be sturdy, but a low infill (5-10%). For the hilt, it was more like 3 shells & 15% infill. The handle doesn't really matter. Layer height need not be finer than .3mm really on any of these prints. The pins I printed extra stiff in order to hold the thing together better. For best results, I usually insert the pins along with some super glue to make the thing feel extra solid. You might need to do some dremmeling or sanding; the platform has to be super super level or there will be some unsightly gaps between blade pieces.

The file is exactly what I used to print. unfortunately, I don't have a higher resolution STL. I would be happy to upload the blender file if you'd like, but I just drew it by hand, so it's a little rough.

So, I think my 11-yr old is going to be Finn for Halloween and this print is perfect for his costume (thanks!). What settings did you use for these pix? # of shells? % fill? layer height? Also, the model file I downloaded looks like lower rez than these pix - do you have the original models that I can use for a slightly higher resolution *.stl (especially the curves of the hilt) or could you upload a higher rez version that doesn't have quite the level of faceting that this one does?

Is the hilt the biggest piece?

Yeah, the hilt has the largest footprint. But it should fit no problem on most printers, it fits (just barely) on my Up! plus, and comfortably on the Replicator.

The other pieces however are quite tall.
