3D Printed Lightsaber Blade Connector

Hello everyone,

As you can guess from the title, I’m trying to make my first lightsaber with a 3D printer.

One of the many challenges I’ve encountered is connecting the blade to the handle. What makes the challenge even more difficult is that the lightsaber I’m trying to recreate is Anakin Skywalker’s in Ep.III, so the connector must be as short and thin as possible.

Do you think it’s possible to make it in PLA?
Are there any precautions I can take to make it more resistant?

Obviously I won’t use it for battles, it should resist small impacts, just enough to trigger the effects on the blade without worrying that the blade might fly out the window :sweat_smile:

Any advice, idea or alternative is welcome :smile:

Since it’s not a skinny neck, it would probably be OK to print in pla. I would print with 100% infill. Pla still flexes.

Another thing to consider is some sort of reinforcing tube. Blades are standard 1" or 7/8" od.

The blade I bought is 1". Is the minimum connector wall thickness you recommend around 1.5mm/2mm or a different measure?
Also, to fix it, do you recommend making a threaded hole and using the screws normally used for blades?

I guess I pictured you printing the entire thing in pla. It’s it’s just a holder that is then going in a saber, 2mm might be ok. But if the total thickness outside the blade is 2mm, I think that is way to thin. Something like 5mm might be better. You could test print a sleeve or something to test.

Also, the further into the saber you can sink the blade, the more sturdy it will be.

Generally, yes, that would be best. But again, pla is still flexible, so it might not be durable enough.

Thanks, I’ll make some tests then :smile:
