Narrow straight staircase 4x8xx8 cm for 3mm laser cut MDF

This is a staircase which is part of my Necromunda terrain collection. It was designed to be cut from 4mm material and has been converted to 3mm. Pictures are of the 4mm version.

When assembling, start with one side and glue in all the steps and supports. Note that one step is slightly smaller than the rest - this is the top one. Then attach the other side.
Note that this piece can be a bit fiddly to assemble. Make sure you make a dry test run without gluing first and sand down any tabs that
