[ ATTN: This replaces a part from the file "Dryer_Segment_5th.stl" from A_Str8's Nesco Spacer]

I simply added a thermometer/hygrometer hole to one of the sides. Print this part and replace one of the 5 pieces to your Nesco Spacer with this part.

The hole size fits a 45.2mm/1.78in diameter thermometer/hygrometer (ebay has many of the same diameter).
