I used Fractalnoise's "Epic Space Marine Staue" (https://www.thingiverse.com/thing:619959).
Since I play Space Wolves I can't stand Beardless Astartees, so I used bendansie's wonderfull "Bearded Yell" (https://www.thingiverse.com/thing:1376314) to borrow the Hair and Beard.
The figure is sized ~5 cm since I will putt it on jpacek's "Gargoyle Fountain for 28mm RPG Games" (https://www.thingiverse.com/thing:2144984) which shall be filled with artificial water.
Keep in Mind, that the original "Honor of the Imperium" Staue, if you wanna use it by it self, without a fountain, is 6" / ~15 cm.
Thank you Fractalnoise, bendansie's and jpacek for your beautifull work.
