This model looks great. I've created a 6mm split version with a couple dovetails and am printing them out now. If everything works as expected I'll upload as a Remix.
Thanks for all your work FDM_Guru!
edit: printed in PLA the split full panel is kind of flimsy, which is no good for a part intended to increase stability. I'll be sticking with the bolt-over part along with the OEM steel side panel for rigidity. If anyone is desperate to get a hold of the dovetailed full panel printable on the mini let me know, but I wouldn't advise it.
