I've been setting my puzzles that all have the standard color scheme up together and decided to grab a few pictures and take pictures of my Lazyman's 3x3x5.
On the left is a 3x3x5, c4y 3x3x4, and on top is mf8 square-1. The middle is a mini maru on top of a rubik's 4x4x4 on top of my cmetric 2. On the right is a storebought 3x3x3 and a meffert's fisher cube.
This is my favorite puzzle right now.
The C4Y 3x3x4 is a great starting point for a proportional 3x3x5, I may make myself one in the future when I have some spare cash.
