60mm round bases that I made alongside my Weeping Crusade range, but kept them generic enough to fit a variety of themes. The stone texture is quite stylised instead of hyper-realistic, which I've found looks better when 3d printed.
There are 3 unique designs so that enough variety can be achieved between a few big models, (remember you can glue identical bases in a different orientation to achieve a more varied look, as well as mirror then before printing for even more variety).
On the underside of the base I've added cross beams, since in my experience the main problem when printing bases is they are prone to warping because of the relatively large thin flat surface, specially when using ABS-like or water washable resins, and beams prevent this issue at the cost of very little extra material. This also facilitated adding a slot for a 3x2mm magnet to use alongside magnetic trays, as well as providing a better surface to glue larger magnets if desired thanks to the curvature of the cross. I've also supported the 64mm version along the sides, which should also help prevent the warping.
EDIT: I just found out GW's "60mm bases" are not 60mm in diameter, but 64mms instead, so I've added 64mm versions of the bases in case you prefer to keep your bases consistent with GW's.
