You can buy them in Amazon, Leroy Merlin… and probably cheaper (but no faster) than if you print this model. I designed it as a challenge. Anyway, you can print only the necessary quantity, instead of buying more than required.

If you slice the model with your own parameters, take into consideration the following printing tips

• Use 5 perimeters: This way, the lines of the clamp are concentric and it is stronger. We need some flexibility to ensure the clamp doesn't break when adjusting it.
• Layer height I chose: 0.2mm as it is a functional part.
• I used PLA.
