A detachable spoolholder.
The slot (?) for the spoolholder comes in 3 versions: with no tolerance, 0.25 or 0.5 mm tolerance for the spoolholder. The last one gave me a good result right of the buildplate.
The slot must be mounted with two 4mm screws or bolts. Size of the head is max 8mm. The slot is slightly adjustable during mounting.
Happy spoolholding :)
