This is a remix of the scalpel holder made by @D_Y_302092
And it is the same as his V1 but made longer to be able to accomodate the longer blades available.
The second picture shows a comparison in size of the original and the remix.
The author remixed this model.
I have extended the lenght of the original model to be able to acomodate longer blades like the #60 and #70.
