A good way to optimize your workflow by puzzeling.

Print instructions

Printed in PLA at 0.2mm (standard Prusa Profile) @ Prusa Mini+

You can scale it in XY in nearly every size you need. (The STL ist too big for the Mini). Too smal pritnts can cause too smal gaps between two parts, but half the size should work nicely.

Be careful by Scaling it in Z - you will scale the thicknes of the floorpate, too.

I modded the STL in Prusaslicer by using the "Hight range Modifier" and some STLs as mod.
