10 inch Rack Shelf Universal

• only normal size can mount 120mm fan
• if you put switch wider than standard 10 inch (around 220mm) switch will place deeper than 20mm, you need to put screw in 120mm fan hole to lock switch in place
• 120mm fan screw or M4 longer than 6mm is ok (i print M4 screw to use)

Small Size 

• small size long 130mm
• i never print this size but i think 3 wall, 20-25% infill might be ok

Normal Size

• normal size long 160mm
• my bed size is smaller than model so i print vertical 45 degree
• i print both model with ESUN PLA+ on default slicer setting 2 wall, 15% infill
