M5 T-Nut 30x30mm Aluminium Extrusion Profiles. Apparently those are hard to find where I live. Not a single store in my town sells those things.
I bet you are asking “But can't you just order them online?”. Well I could, but then I'll have to wait a week before I got them. Fortunately my trusty Prusa MINI is here to save the day.
Before you print
The 3D printed T-Nut is not in any way comparable to a real T-Nut made from, you know, metal.
Assembly
Do not skip steps, or execute them in different order.
You will need:
1 x 3D Printer
1 x M5 Nut
1 x Pack of Gummy bears.
Glue (optional)
