Simple Minecraft block

I made this for my grandson because he wanted a Minecraft Rose to give it to someone but being new to 3D Printing I could not find one. Also I only had red PLA and a bit of white PLA so I designed this block so he could make red blocks for the flower and white for the stem and colour them green then glue them together. The holes and pimples help line them up so they stay put when glued. I think they line up because he didn't say anything about them not doing so.
Updated block with a bit of tex
