Homemade CNC Nut With Thermo Moldable Plastic Enclosure

I built this thing to use it in a CNC prototype. I also wanted to test thermo moldable plastics in this project.

The objective is to build a nut holder that can be attached with screws to a wood base. This nut will be driven by the threaded rod of the CNC Y axis.

The steps are very simple and the pictures describes the process much better than words.

I built a mold with aluminum profiles.
This box will hold the nut as shown in the images.

I then placed the plastic balls inside the box and melted them with a hot gun. I set temperature at 70 celcius degrees and heated the plastic until it melts and becomes transparent.

Once it get cold, dissasemble the mold and the nut holder is ready to install.
