Stronger Downholder for coffee machine brewing units

thingiverse

First I designed an extra pad to prevent the printed Downholder (Version from Cynr1c) from twisting inside the brewing unit. Which also solves the Problem. I've added the extra Pad - if you still want to use the original part designed by Cynr1c. Then I decided to merge them together inside one stronger part. I've printed it in PLA with 70% infill and supports and it is working fine for me. Print it with the big flat side facing downwards. The V2 had an extra pad directly below the rubber element. I used this one until the rubber nipple of the element was pressed inside the venting hole causing another breakdown of another part in the machine. Then I decided to change the design back to the original geometry - so the pressure of the rubber element is not increased by the extra pad. V3 with a new rubber element is working fine for me!
