Description
With some additional parts you can make a perfect cable spool of a empty Prusament spool. It is made with bearings and rock solid. For example capable of holding 30m patch cable or what ever you like!

I propose printing with a 0.6mm nozzle. Beacause of print speed. The print is tested with this values:
Material – Prusament Prusa Orange
Nozzle 0.6mm
First layer 0.25mm, Layer hight 0.25mm
Middle Part, End Pieces and Angles,: 4 perimeters, brim, 20% infill
Conus: 3 perimeters, 15% infill no brim
Crank Grip and Back: 2 perimeters, 15% infill no brim
1x Middle Part
3x Angle
3x Endpiece
1x Crank Grip
1x Crank Back
1x Threaded Rod M8 x 130mm
1x Drive in nut M8 ISO 6930, 11mm height
2x Nut M8 DIN 934
1x Cap Nut DIN 1587 or a normal nut and some screw glue
1x Spacer M8 DIN 9021
1x Screw M3 x 15 or 3,5mm Chipboard Screw
2x Bearing 608 2RS (8x22x7 mm)
1x Aluminium Tube 8mm x 130mm (Middle part to handle)
2x Aluminium Tube 8mm x 120mm (Middle part to foot angle)
2x Aluminium Tube 8mm x 90mm (foot angle to foot end)
1x Aluminium Tube 8mm x 70mm (handle)
13x Screw M3 x 10 or 3,5mm Chipboard Screw
Follow simply the pictures. The numbers of the pictures give the order of assembly. I have also written comments for most of the steps:
You can cut the aluminium tube with a tube cutter
Place the Crank Back. The plate only fit at some place!
Remove one side of the filament spool and use the Crank Back as a stencil for drilling. Drill a hole depending on your screw. Something between 3mm and 4mm is possible
Align the printed parts and drill a hole through one half of the tube
Fix all tubes with screws. Save the End Pieces for the next step. Take the screw you like. M3 x 10 and drill a thread in the tubes or quick and dirty some 3,5mm – 4mm Chipboard screws. Chipboard screws are harded and they cut easy an alumium tube
Align the End Piece
Assemble the handle like the feet. Adjust the handle and drill the hole for the screws.
Place the drive-in nut over the openings
Place the threaded rod in the drive-in nut. Put first the plate on the rod and then two nuts on the other side of the rod. The turn both nuts against each other.
Now you are able to drive the drive-in nut in the middle part.
Losen the two nuts and leave one nut on the rod.
Adjust the rod and tighten the remaining nut a little.
Place the second nut on driv-in nut side and tighten the system now.
Place the bearing and then the assembly on the threaded rod
Place the Prusament Spool on the Conus
Fix the spool with the second Conus
… and the second bearing goes into place
Fix the the system with a cap nut
May you need a hole for one end of the cable
Finish !
