Here is my home made version of the old epic Skullhamma, upsized to W40k scale.
You will get a nice and big battle fortress, mostly similar in size as a land raider.
For those who want to modify it, I can provide STEP files.
Get ready for the battle! Waaaaaaghh!!!
Edit 24/02/22 : I add a cost calculator to estimate the cost of the print, regarding your favorite material and electricity cost. Mine cost me 9,50€.
Edit 03/03/23 : Finally it is complete!!
