For our parts we found that we needed to add .3mm to all pockets and holes to go from Pollen's models to FDM

With the SLA printing on our Form2 we found it may have actually shrunk slightly, although the real issue is that there are several places where proper tolerancing by Pollen never happened. For example there is no tolerance in the magnet pockets for the antennas. Generally elsewhere the tolerance is .1mm, and while that may work on SLS, most of our SLA and FDM parts needed modification and tolerances added.

Here is a video by @Dan O'Mara about his modification to parts to go from the Pollen designed Reachy models to models ready to print on FDM consumer 3d printers.

No servo horn in this shot. You can add 2.5 mm to the bottom and drop the screw head shelf 4mm
