I sliced this part in Cura in Repetier host .
layer height 0.2 mm
Infill 10% , but probably higher for more strength jobs .
Brim and supports set to everywhere .
possibly just print or abort after first few MM high have printed . then compare the wall thickness to your extrusion . Mine is 1.4mm thick , yours my be thicker. so print shallow test , and adjust the scale of the part to match your extrusion stock.
