Vertical Spool Holder (modular) for Benchy Carousel (30-70mm, M6-M12 rods)

thingiverse

A few days ago I designed my "Benchy Filament Sample Carousel & Sign-Generator" (https://www.thingiverse.com/thing:3037172). To build a stable spool-tree, I need something that holds them in place while every spool can still be rotated easily, allows for the addition of more spools later, and can accommodate different spools with variable inner diameters but minimal space between them. It also needs to be optimized for 3D printing (most parts should be printable, material reduction is key) and use threaded rods (also variable diameters). So I came up with the idea of a strong base where a nut is glued in that can hold M6-M12 threaded rods. Spools with inner diameters between 30-70mm are compatible, and the washers are independent from the threaded rod diameter. If you're not using metric values for screws, try printing one of the TEST-files I uploaded and use the one that fits best. Alternatively, compare the values here: https://en.wikipedia.org/wiki/ISO_metric_screw_thread#Spanner_(Wrench)_sizes. Unfortunately, I'm still stuck on Tinkercad with my designing skills, so I couldn't create a customizable file for the washers. However, I added a bunch of them growing by 2mm each (30mm, 32mm, ..., 68mm, 70mm). Here are the parts needed: * (*) 1x threaded rod - 0.5m-1m recommended (size: M6-M12) * (*) 2x nuts - or 1x nut and 1x butterfly nut * 1x base (model depends on the size of your rod - no fun intended) * 1x connector (same size as base) * (**) 1x connector * (**) 2x washer (model depends on the inner diameter of the spool) (*) = not printed (**) = per additional spool
