you need: 

                1x steel rod D10mm or a                     threaded rod M10 600mm   

                1x drain pipe D 50x1.8  550mm

                4x cylinder head screws     M4x16

print:

                   1x Multispulenhalterung vorne (front)

                1x Multispulenhalterung hinten (back)

                2x Rohrstoppel für Rohr D50x1.8

print the parts strong enough to carry the weight of several full spools of D200mm.

depending on the printer calibration, it may be necessary to scale the printed parts minimally.

mount the two brackets in the enclosure back at the rear and front at the side next to the door in the existing M4 holes. (4x M4x16 screws)

Note that the two M4x20 Screws (door attachment) must be shortened to M4x12 (see photos) beforehand, otherwise the screws would cross.

put the parts together and insert.

note that the enclosure control cable must be routed up high so that it does not cross the spools.

also note that when the holder is fully equipped, the print height (Z) is limited to approx. 280mm in the rear area of the printsheet. (Collision)
