This is just a remix, where I offer two different versions of the same backplate. The first version has a wider wood grain (tan colored plate in photo), and the second has a more fine grain on the face (gray colored plate in photo). Both should print out pretty nice with Wood PLA.
Feel free to use it as you wish. :)
UPDATE I fixed an issue with the second version. I didn't realize the texture tiles I used weren't aligned, so I fixed that. The grain will cause voids under the vertical components by a half mm, but your printer should be able to bridge over that. Thanks for understanding.
