Comments
In this chapter, we will assemble the spool holders. Before proceeding, note that there are two types:
⬢1. Current Injection-molded spoolholder
Currently shipped in the MK4/S or CORE One versions. Continue to Injection molded spoolholder: parts preparation
⬢
2. Legacy vacuum-formed spoolholder
This old version used to come with the first MK3S versions or older upgraded units.
Continue to the Vacuum formed holder parts preparation
If the large portion of the box is occupied by the rectangular black trays, you have the first version, the older vacuum-formed spoolholders.

The Prusa Enclosure V2 - MMU2 appears to use the aluminum rods from the Classic vacuum-formed spoolholder, but I received the new injection-molded spoolholder. Does anyone know the dimensions of these rods?

Won't lie, "older" vs "new" doesn't feel very nice if you have an older version in the box you just received.

There is one more Prusa Original version of spoolholder which followed vacuum-formed version as an upgrade. It is made from laser cut plexi and reused parts from vacuum-formed spooldholder. However the PTFE tube holder hole is a bit different. Assuming the spoolholder remains intacted and will be reused as is.
