I am slowly acquiring my BOM and starting the process of making this sweet robot arm. The manual says to drill and tap the 3D-printed plastic, but I usually use heat-set inserts for things like this. Is there any reason not to, or is drilling and tapping used just for simplicity's sake?

I completed the mechanical build of the arm this weekend, and am starting the enclosure. The base pieces that go under J1 and receive the motor plugs and the cover pieces for J5 seem to be the only candidates for threaded inserts. No inserts used yet, but the base pieces should be an easy retrofit. The J5 shroud is super tight and lacks sufficient wall thickness for an insert. This part is easy to redesign/replace later on...
I won't get to the cabinet until later in the week and I will see how it goes..
