if print-in-place models print seized you don't need to resize or redesign them but can fix it in the slicer. First reduce your first layer flow by a few percent until elephants foot is gone. If not fixed, reduce overall flow a tiny bit enssuring the top surface still looks flat - chances are you're overextruding a tiny bit. If still seized, it likely needs more tolerance - increase the slicer setting called Horizonatal Expansion in Cura or XY Size Compensation in other slicers. This will increase the size of internal holes without expanding external perimiters so effectively increases tolerance. You shouldn't need any tools to free it if it is designed well.
I printed a thumb ratchet and it was not wanting to free up. I tapped it with a hammer on the flat side till it started wanting to move. Also, A little oil helps free up moving parts.

Have you calibrated your extruder steps and flow rate lately?
