Coffee Knock Box

This is a coffee knock box I designed. It measures 130mm wide and 120mm tall, perfect size for a home knock box. I placed a 10mm steel rod down the middle of the "bar" for strength an added weight.

EDIT: The 10mm rod measure about 9.7mm. The ID for the bar is 10mm. I used a heatgun and a hammer to coax it down the middle. You could also try printing slightly enlarged. I think the tight fit is good though.

Print Settings:
Layer height - 0.3mm to make it a little quicker
Infil - 20%
Nozzle - 0.4mm
Outer layers - 3
Top bottom layers - 3

Post pictures if you print it! Let me know what you think!
