I’ve printed two books using the Lulu service. (One for Tyrone)
When they arrived, I noticed some faults.
Lucky Lulu will be printing them again for me.

And I’ve been busy building a Mega Tower with 4 Motherboards.
This will have a superb processing power! .. not.
It houses some old motherboards for hardcore machine coding on real old hardware.

Todo:

• Rework on the cables
• 3D print an information plaque on the front of each board
• Add a control panel on each board
• Maybe some dust cover would be nice

I can remove the boards, and place them on a table.
I’ve made some custom feet for them. Twist and lock by my own design.

The openscad files:

The locking is done by making the cylinder slightly oval by 0.5mm

difference(){
	difference(){
		difference(){
			difference(){
				rotate([90,30,0])
				cylinder(r=30, h=10, $fn=3);
				translate([-20,-20,0])
				cube([40,40,40]);
				}
			rotate([90,0,0])
			translate([0,0,-10])
			cylinder(r=5, h=30, $fn=200);
			translate([0,-5,-10])
			cylinder(r=7, h=30, $fn=200);
			}
		translate([18,-5,-12])
		cylinder(r=4, h=30, $fn=200);
		translate([18,-5,-22])
		cylinder(r=2.2, h=30, $fn=200);
		translate([-18,-5,-12])
		cylinder(r=4, h=30, $fn=200);

		translate([-18,-5,-22])
		cylinder(r=2.2, h=30, $fn=200);
		}
	translate([9,-20,-20])
	cube([40,40,40]);
}

Note the resize for the oval effect

resize([14,14.5,10])
cylinder(r=7, h=10, $fn=200);
translate([0,0,0])
cylinder(r=9, h=3, $fn=200);

When designing above, I also made new knobs for our stove.
Using the white dot, you can see which burner has which knob.
