Anet A8 - Raspberry PI 3 B+ and Step down USB power holder

This is a scratch design with the general idea taken from the 2 sources. Thanks.

You will need:
4 x M3x8 to mount a step down board for Raspberry PI 3 B+.
3 x M3x8 to mount a step down board for USB power.
3 x M3x18 to mount to frame.

USB step down board I used:

This mounts to the inside right frame upright.

UPDATE 31-Dec-2018
Added an extension to hold a Raspberry PI 3 B+
Added frame mount point above the Raspberry PI
