The file 'Universal Slot 1 Bracket (SECC) 3D Printer Model' is (STL) file type, size is 289.8KB.
I'm not really sure if my remix is an Universal SECC Bracket, but I designed it to fit the heatsink of my Pentium III cartridge, as shown in the picture.
I've also designed the mount and nuts to fix the bracket on the motherboard. I recommend to print these with a 0,16mm (or less) layer height.
Note the orientation of the mount, in order to not overlap with the motherboard pins.
They are sturdy enough printed in PETG or even PLA+, but you can use your metal nuts and bolts, if you prefer.
Print the bracket horizontal, as seen in the picture. You will not need supports.
