Lack Stand Corner Mount Tool less

This is my first try in creating CAD for 3D Printing and actually for CAD at all.


I wanted to stack Ikea Lack Tables on a furniture Roller, i bought at Amazon (asin=B00B8NVWOQ, Modelnumber=20135801).
To stabilize the first Table on the furniture Roller i edited, rendered and exported the .scad File as .stl. I did this in OpenSCAD,

The furniture Roller has Dimension of 585mmx585mmx145mm.
The Wheels have Breakes
The Wheels are 48mm and 49mm away from outer Corner.
The Ikea Lack Table Legs are 50.5mmx50.5mm (possibly 0.5mm thicker).

I still need to create round Edges. I dont give up on a nice smooth Look. But Minkowski isnt an easy Task.

I am not yet sure with what Settings i will Print that Item.
I have a Geeetech A10T and a Anycubic Mega Zero 2.0.
I will make use of Octoprint, AstroPrint and Cura Slicer 4.8.0.

I am thinking on making it sturdy.
