Ikea LAGKAPTEN 8020 T-Slot Extruded Aluminum (20x20) Under-desk Mounting Brackets (paramateric)

My Ikea LAGKAPTEN Desk can't hold much weight in screws, but I can bracket 20mmx20mm 8020 t-slot extruded aluminum rails onto it easily with this adapter.

I have 2 different sets of options in the provided STLs:

1. The T-slot profile for different vendors (they are notably different.  
   - 8020.net: the classic, 5mm opening
   - tnutz.com: much cheaper in the US, 6mm opening
2. The extra clearance below the desk:
   - 0mm: Just mounts flush against the desk
   - 4mm: Allows you to have an under the desk openGrid Lite for Underware plates between the desk and the extrusion

Uses 1 to 3 M5x10mm screws to hold the rails in place.

The model is made using OpenSCAD and utilizes the BOSL2 and bosl2-parts libraries
