This holder will sit under your Force Tamper rubber tamp mat to reinforce it. It is designed to match the angles and aesthetic which providing additional structural integrity. I look after the coffee machine for a community group and the rubber mat is cracking and falling apart a bit. I printed it at 100% infill with PETG because sometimes people leave everything on top of the coffee machine.

THIS MODEL WILL FIT A NEW OR UNDAMAGED RUBBER MAT. FOR CRACKED OR DAMAGED RUBBER MATS THAT ARE LARGER THAN NEW USE THIS 1MM LARGER MODEL: https://makerworld.com/en/models/494341
