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.

Step 1: Filling the Mold With Thermo Plastic Balls

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.
