I need some help sizing this please. When I open it in Fusion it is only about 9 mm long. how do I correct the scale?

What is the size of the screws you need to attach the neck to the main body?

Thanks

Thanks so much for posting this. I plan to make one for my brother. I downloaded all the files and noticed that the .dxf does not look complete. I'll tinker with the STL files and see if I can somehow export to .dxf or *.eps. Thought I would mention here in case I am missing something and see if anyone else was having the same issue. I plan to import the vector file to Vectric Aspire and setup all toolpathing there. Thanks again !!

First of all, this is awesome! I can't believe I just now saw this on here! I plan on making this with my students ASAP.

Anyways, I was wondering if you could share where you got your aluminum panel? I can't seem to find a good source to order from.

Thanks!

Hi Corben33 - Thanks! You can usually find ACP at your local sign supply store (ie. the place that sells coroplast/ACP panels for sign shops). In the US a popular brand is Dibond - though there are generic ones too. The one in this video is a Dibond RED 3mm ACP. Please post pictures of you and your student's ukuleles! -Nathan

what other materials could you use for this? also what is the white bar on the 3d printed bridge and where do I get it?

That's the cool thing about CNC machines, just about anything. The soundboard can be solid metal, wood, plastic, acrylic, etc. Same for the main body and neck. We've used maple, basswood, and douglas fir.

The white bar is the saddle (usually made from bone or plastic).

Thanks for the info. I will definitely post pictures

My workflow is in mm and when I load this into meshcam it's way too small. I think the conversion is 24.5, is this correct (before I cut into some nice wood). I really want to mill one of these.

Hi - 25.4 is likely the correct conversion and should get you to where the body is 226.611mm at the longest dimension along the length of the main body (ie. not including the neck). Let me know if you'd like me to save a metric version of the STLs - happy to do that.

Edited to correct mm-to-inches

Oops I meant 25.4, when I scale it I end up at 226.597 so I think that's about right. I think I have it, thanks for the confirmation.

Anytime - Yes, that's within the precision of the BREP to MESH (STL) conversion.

Right, 25.4 - I did the same thing!
