Corner clamps for easy cabinet building

[Christofix]

Hello,

Because I want to make boxes and cabinets soon, I started looking for a handy tool for making corner joints.
This is what I made of it.
The clamps are very easy to make yourself, no complicated conditions or materials. Due to the MDF plate on the top, the clamping pads do not fall out when used upside down.

Hopefully, this will also help you.
