25mm wargaming bases, both plain and slotta.
Suitable for Warhammer 40k.
Useful for when you buy metal miniatures off of eBay and they don't come with a base.
The photos of the printed slotta shows the difference between "right side up" and "upside down" prints. The left one was printed with the flat against the bed and no support, and the other was printed with the bottom against the bed with support material underneath inside the void. Either way is good, but the "inverted" setup with no support saves on material, and you'll be piling basing materials on top of it anyway.
Add your dude to the slot. The slot measures 19.5mmx2.4mm, so it should fit for any GW model. If not, just open it out with a needle file.
Bashed together in tinkercad as a learning experience.
