These are 4 C Beam 40x80x1000mm linear lead screw actuators arranged in a square but facing towards the center. I want to connect these four together around the perimeter with something like - Part Number: 40-4080 40mm X 80mm T-Slotted Profile - Six Open T-Slots How can I do this and with what part numbers? Bonus info if possible is I want to create a table with wheels under those so I can roll the device around. The table part I can see some examples but how to nicely mount those towers to it? It is a larger format 3d printer in the end.
