PID CONTROL BOX

PID 1.0 HAS BEEN COMPLETED, TESTED AND PRINTED. ITS DONE!. ALL OTHERS ARE BEGINNING STAGES ALSO LIGHTER LID.
This is a temperature control box with PID, SS solid state relay, K type thermocouple connector and light switch/plug combo with 40mm 12 vdc fan. Just finished! If printing in Cura set to support everywhere, lower it to 10% density and raise overhang angle to 88%. will update if those settings work when I print it.
UPDATE!
Sorry just noted 40mm fan stuck in a bit, made it flush inside and out!
As a personal preference I would have fan blowing out heat. perhaps I 'll make a printable?washable filter and slide it on intake by SSRD! HUM!
UPDATE 1/6/2019.

1/7/2019.ADDED INPUT HOLE, MOVE FAN UP AND MOVED OUTLET AWAY FROM EDGE AND CLOSER TO PID ADDED EXTRA MATERIAL TO FLUSH THE PROTRUSION OF OUTLET AND AD
