L-shaped staircase 8x8x8 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 MDF and has been converted to 3mm. Pictures are of the 4mm version.

When assembling, glue together the two inner sides at an 90 degree angle, then glue in all the steps. Note that one step is smaller than the other - this is the top one. Finally, attach the two outer sides.
Note that this can be a bit fiddly, Make sure you make a dry fitting first without gluing, and sand down any tabs t
