Does anyone know - what type of screws are best to use for boring into plastic?

i am in the process of making this item. Everything is printed and now in assembly. Please note that it can take up to a month to get the pickup assembly from China - mine to 16 days but the official estimate is 1 month. I also did a test stringing of one string as a test and I broke the string. This is common knowledge amonst violiners - but when tuning the top (smallest) of the strings - be careful and adjust slowly.

Comments deleted.

Can you please provide more specifics on the M8 Threaded Rod and screws used in the assembly of this violin?

I just got through this step - I got a 5/16 rod from Home Depot that was too long. The 5/16 is slightly larger than the hole provided - so I used acetone to wipe the rod cavity to make it "wet" then I ended up threading the rod through the entire part - including the bolt in the neck. I twisted the topmost piece until it went no further, then I threaded the middle section. When it was very close I used some acetone to make each part sticky and then rotated them together. Finally I needed 130mm of screw sticking out to provide space for the 3rd stage and the final screw. I did not use a lock washer (probably should have) BUT I used abs slurry to seal the two bolts. I will post a few pictures when my project is complete ( NOTE I USED ABS )


good work for the designe.

but the electronique on your ebay link is not available.

Could you tell us the name of this electronique product please?

I find your violin to be the most beautiful on thingiverse. Would you be able to provide the same design in 1/4, 1/2 and 3/4 sizes?

Any chance for a 5 string violin? Or could you post the design files? (I could make the adjustments myself - widen the fingerboard a little bit, extra tuner, etc).

I'm really enjoying the low C on both my 5 string violins,but none of them are electric. I'm dreaming about making your design and tuning it a octave low for that cello range.

Hi , first of all , nice work , is a really awesome creation , i am printing this violin for the birthday of my sister and i have a question, where i can buy the pegs that are in your violin? , i can buy the other parts and the electronic by your printing details (Thank you :) ) but i cant find the pegs .

Thank you and nice work ! :D

Thanks for comment.
You can get them from musical instruments store. I got them, at school where i took violin lessons.
These are Grover brand 3x3 tuning keys for electric guitar.
I hope that soon get.

Hi again , i have a little bit problem with the electronics, i dont understand where put everything , in the photos of the violin it seems that you welded the electronics to the tuning keys , but i dont have any idea the parts exactly , you followed a tutorial for the electronics?

PD: the rectangle thing that comes with the electronic components is usefull for this violin?

Thanks in advance and sorry for much questions.

Hello, the rectangle is the receiver or microphone and must be under the bridge to receive vibrations.
You have to desolder and pass the two cables through the hole under the bridge. then you solders the wires again.

and i have to glue with epoxi the britge on the microphone? , i question because is a delicated operation and i dont know if epoxi will distort the signal to the microphone.

Thanks in advance.

Do not. the bridge is held in place with the pressure of the violin strings, As with an acoustic violin.
Do not use glue.

This is awesome. Really cool to watch your violin evolve over the versions. Great work!! Got any videos?

Hi David.
Thanks for your comment.

so, you and others have helped inspire me this violin.
Soon I'll upload a video.
thank you.

Also, not printable by Replicator 2x :( the bouts are too tall for the printer size... damn

Any 'proper instructions' on how to put this together? how many total parts are.... or is it simply just print one of all the parts in "thing files" and put them together with one long 8mm threaded rod and nuts, add the electronics, buy your bow and that's it? if so I wanna do this ASAP!!!

But do the strings come with the electronics kit? or are they also extra like the bow?
