Scalable Spool Holder

This is a thing meant for those who has an spool holder system using the 608 Bearings (whatever you are using, this is not the attachment to the spool, just the holder of the threaded rod)

You can build the stand as you want, there are just 2 parts which are half of each piece/ corner/ join.
The idea behind this is to print once and then scale on demand by getting longer steel threaded rods.

Hardware:

The entire thing could be done using M8 or 5/16", just pick one or the other don't mix.

Steel threaded rod:

• 6 pcs of equal length (2 sides of 3 rods which are equilateral triangles)

• 3 pcs of equal length (the center of the spool and 2 more for stability)

• 32 x nuts

• 20 x grower washers (for holding the nuts)

• 20 x special washers (thinner)

The rule is on each join: Plastic | Washer | Grower Washer | Nut

The Washer is to distribute the force into the plastic and avoid damage it; and the Grower Washer is to get a force constantly applied againts the nut and the plastic so nut wont come loose later on.
