This is an "Unseen" BattleMaster (BLR) from BattleTech. It is based on the old school design from Dougram. I mostly referenced the old mini figure and some artwork. Printing is a bit tough with the arms so I detached them. I'll probably make the file available on TINKERCAD for modification.
My first test print had some flaws but some great detail as well.
My test print next to the old mini that it was based on.
