Substrate tamper (dụng cụ nén substrate)

This is a 2 part model for ease of printing. Both print quite quickly and I recommend 25% with at least 3 walls. PLA or PETG, I'm using PETG.

Screws together with 2 M4x8mm button head socket cap screws, but anything similar will work. 

You can see in the pictures that it can very easily embossed/debossed in most slicers.
