2020 vibration damper bolt-on v5 (for mini Kossel)

Update: After some months of use, I noticed the v5 lost some of it's shape, because PLA flexed under the growing weight of the Kossel mini (with 1kg spool on top, and pcb heatbed+4mm glass).
It still works fine, but the lower tabs now rest flat on the table, instead of being on their tips.

So I made a v6 that prints with slanted inner tab (so no more cutting needed), and I also made these a little bit thicker, to better hold the weight.
