I got tired of trying to print this in ABS without the deck plate splitting, so i thickened it 2mm and added 1mm x 2mm strakes to the sideplates. You may need to round the corner of the slider feet to clear the strakes. If they don't work as is, I'll make a modified version here in a minute. Printing this now.
