Spool holder (tabletop)

To experiment with higher speeds on my printer I wanted to remove the spool mounted on top. If you have large spools (1kg of filament) mounted on top of the printer vibrations will amplify. I made this simple spool holder to be used with the filament guide. The setup is simple and works very, very well. I've been able to speed up with a couple of hundred percent without noticable loss in quality, and the printer stands perfectly still. This also helps with noise. The spool is mounted on a slant, this makes for a tangle free feed to the printer (automatic retraction :). This does not present enough friction to make any difference what so ever. The spool hubs is not my design, it's by AndrewBCN, https://www.thingiverse.com/thing:586673. I've printed and used them before and they work well. The nut knob has a captured M8 nut. I've run this setup for many hours and have not encountered any problems at all. Dimensions of aluminium plate: Width: 95 mm Length over all: 210 mm Bend at: 120 mm (a little past 90 degr gives a good angle M8 rod: 130 mm (takes my largest spool) Drill the hole, in center, as close to bend as possible. For the filament guide I used a bike spoke (2 mm stainless wire). Heat it and bend it around a 10 mm drill bit.
