Spool holder

This is a new design for a spool holder over a t-slot. Materials:

- 1 x Spool holder cube
- 3 x 5mm screw
- 2 x t-slot stoppers
- 1 x 5mm nut
- 1 x 8mm screw rod
- 2 x rod stoppers pieces (palometas)
- 2 x 8mm nuts for the rod stops

Mount cube on the t-slot by means of the t-slot stoppers and two 5 mm screws. Then insert the 8mm screw rod in the cube and fix it with an other 5 mm screw (remember to insert the corresponding nut before in the cube). You can install you plastic spool using the corresponding adapter and finally you can mantain it in place using the rod stoppers (each using a 8mm nut). Two rod stoppers are needed to avoid the spool to "walk out" of the rod, for this purpose both rod stoppers should be tight together.
