kt-6808 jewelry tumbler replacement parts

there are a few models here, i made them to fix an old, beat-up tumbler i had (kt-6808 3kg tumbler): 

1-a bottom plate cover (you will need screws, i think i used m3)

2-lid fastener with an offset rod hole to apply preassure on the lid

3-a knob

4-a replacement o ring band for the sides. here you should use a rlexible filliment like flexPLA or something of this sort.
