Some modified parts for the BEAR upgrade.

1. An adjustable foot my design to handle uneven tables

2. An adjustable Y belt holder - this is a modification of a design by ZBROZEK (https://www.thingiverse.com/thing:2995737) to allow his adjustable tensioner to work with the MK2.5

3. Side boxes. A remake with rounded interior, inspired by "Bear upgrade side box by Vlastimil3" thing:3568289

ADDED: 4) Metric foot - uses metric 5mm-25mm bolt and nuts (3). two nuts used to lock bolt head to foot (not shown) and bolt adjuster nut. Glue foam. cork, whatever to bottom of foot to control sound transferance. A piece cut from a flip-flop should work well.
