T-Nuts

In this design I have used 3 types of T-Nuts

1. M5 T-Nut Square – 75 Pcs: Link
2. M5 T-Nut OpenBuilds – 25 Pcs: Link
3. M5 T-Nut HammerNut – 100 Pcs: Link
   M4 T-Nut Hammer Nut for miscellaneous addons – 100 Pcs: Link

The reason for this is that I wanted optimal alignment for all parts. The XY motor brackets and the XY corner idler brackets have a profile that centers it into the V-Slot. This means that the square T-Nuts will interfere with this profile so you want to use OpenBuild T-Nuts or just drop in nuts as hammer nuts or spring nuts – all M5

Here you can se the profile and the OpenBuild nut for better understanding

Here you can see the 3 type of nuts
