Tamper helper 54mm Espresso SAGE / BREVILLE

Sage / Breville 54mm Tamper help
If you - like me - usually mill your espresso beans in 2 steps and flatten the coffee-powder inbetween, this model saves you the work to take the portafilter out of the mill, flatten the ‘mountain’ and place it back in. 
Note: this is not for tamping! just to flatten the mountain with low pressure to avoid overflowing during grinding coffee. I use mine on the Sage SmartGrinder Pro and have it set to ~2 * 6s to get ~18g. After the second time, I use the normal tamper.

53mm diameter to fit 54mm baskets like on the Sage bambino Plus
~14cm angled handle (16cm total size of the gadget)
Quick creation via Thingiverse; original STL and Dove-tail-Connection version for easier printing included.

Note: the dovetail requires support! (the bevelled edges benefit from support as well).
printed as shown in Yellow+Black in 44minutes on a Snapmaker U1 with supports.
