In Longer Advice to Rahula Buddha details all the elements including space.
It is a long discourse so I will only quote a portion here:
Rāhula, the interior earth element is said to be anything hard, solid,
and appropriated that’s internal, pertaining to an individual. This
includes: head hair, body hair, nails, teeth, skin, flesh, sinews,
bones, bone marrow, kidneys, heart, liver, diaphragm, spleen, lungs,
intestines, mesentery, undigested food, feces, or anything else hard,
solid, and appropriated that’s internal, pertaining to an individual.
This is called the interior earth element. The interior earth element
and the exterior earth element are just the earth element. This should
be truly seen with right understanding like this: ‘This is not mine, I
am not this, this is not my self.’ When you truly see with right
understanding, you reject the earth element, detaching the mind from
the earth element.
You can go and read it yourself. And it was also given as an answer in the link you provided.
Other suttas include:
'A boil,' monks, is another word for this body composed of the four
elements, born of mother & father, fed on rice & porridge, subject
to inconstancy, rubbing & massaging, breaking-up & disintegrating. It
has nine openings, nine un-lanced heads. Whatever would ooze out from
it would be an uncleanliness oozing out, a stench oozing out, a
disgust oozing out. Whatever would be discharged from it would be an
uncleanliness discharging, a stench discharging, a disgust
discharging. For that reason, you should become disenchanted with this
body.
AN 9.15
And why, bhikkhus, do you call it form? ‘It is deformed,’ bhikkhus,
therefore it is called form. Deformed by what? Deformed by cold,
deformed by heat, deformed by hunger, deformed by thirst, deformed by
contact with flies, mosquitoes, wind, sun, and serpents. ‘It is
deformed,’ bhikkhus, therefore it is called form.
SN 22.79
"If the permutations, signs, themes, and indicators by which there is a description of name-group and form-group were all absent, would designation-contact or resistance-contact be discerned?
“Yehi, ānanda, ākārehi …pe… yehi uddesehi nāmakāyassa ca rūpakāyassa
ca paññatti hoti, tesu ākāresu …pe… tesu uddesesu asati api nu kho
adhivacanasamphasso vā paṭighasamphasso vā paññāyethā”ti?
