Knockbox - for Coffee and Espresso grounds

Print this knockbox in any material you want, I chose PETG.

No Supports needed!

I added a colour accent by layer-based colour change.

I used a 20mm wooden dowel. I measured it with calipers, came out at 19.7mm, which I designed for. You can pop the dowel in and out for cleaning.

There are endstops which also print without supports, a sacrificial layer needs to be punched through when using wood screws during assembly. I added an assembly stl for reference, as well as STEP and inventor ipt/iam files.
