This is a basic scalpel holder built to hold 3 scalpels. The inital design in built to hold scalples with handles up to 7mm in width though this can easily be adjusted in openSCAD. I've estimated a per unit cost of $0.31 using a 10% infill and a 0.3mm layer height with no support. I've seen similar holders online go for around $0.62 per unit so there is approximatly a 50% savings there. I will probably be updating this in the future to possibly have some more features and hopefully make it fully customizable.
