DIY Violin


Here I leave you my last attempt at making a laser cut/3D printed violin.


The design is based on a design by Felix Savart, and the dimensions are those of a regular 4/4 violin. I’ve made the necessary adaptations to adjust it to the fabrication methods available. I’m sure that with the knowledge and experience acquired through the process some improvements can be made, and if I get the opportunity to give it another go I probably make it easier, faster and better.


Most of the wooden pieces are 5mm poplar wood except for the top and bottom plates and the two boards on the neck which are 3mm poplar wood. There are also PLA 3D printed parts in the neck and the pegs and to hold the bottom string.



The pegs are made from a 5mm bolt with a 3D printed part with an hexagonal hole to fit the bolt head. I made a hole on the bolts to fit the strings through. The pegs go through a pair of self locking nuts each to simulate the grip of the regular pegs. The nuts are embed on an custom designed 3D printed part that fits in the head of the neck.



The neck is made of five layers of 5mm boards. Those boards are a bit higher in the middle to aid support the two 3mm boards that go on top. Those two boards are glued on top and the gaps filled with glue. Finally the boards are filled and sanded to give it a nice curved surface.



The box is made of a top and a bottom plate separated with a set of five perimetral layers. the top plate has glued a bass bar and between the top and bottom plates there is a pin that acts as a sound post. Also the top plate has the mandatory “F” holes.



The strings are attached at the bottom through a plate that is tied with a rope to a small 3D printed part screwed at the bottom.


That plate has the four microtuners that are usually used by non experienced players to ease the tuning process, in this case it will help with the inherent play of the pegs nuts.


The bridge is held in place by the pressure of the strings which also took my attention the first time I found out. Finally the strings have to be fixed to the microtuners in one side and the pegs in the other side and then give each string the tension needed for each note. From this point on, I have no idea what I’m doing so the next video is going to be of my friend Xabi trying out the violin (he knows how to play it).
