Filament Spool Stand v2: Test Creality K1

Previously mentioned, the Creality K1 printer was delivered to me a few days ago. It is amazingly fast, and in a few days I was able to create a number of projects that would normally take me a full week with other printer models. It's impressive that such amazing speed is not at the expense of print quality.

Previously, I had not even considered using a printer for such tasks. The previous model I partly cut out on the laser, while the Creality K1 with its 600 mm/s printing speed allows me to not only create but also print all the parts (well, you could print the previous one, but it's too much for my nervous system). Also, I've been wanting to try T-thread screws as axles for filament spools for a long time. Metric nuts and studs are not very suitable for this purpose, as they stop quickly when rotating, they simply go into resonance. T-nuts, on the other hand, provide a more stable and smooth rotation all the way to the stop.

Since I have the printers on my desk and under a shelf, I have no ability or desire to mount the spools behind them. This is neither convenient nor practical. So I opted to use a stand that allows the filament to pass through a hole in the shelf where the filament is mounted. Also, the first version of the stand was converted to use T-shafts with nuts.

For the Creality K1, I have not yet installed a filament end sensor; instead, I inserted a small piece of filament into the sensor itself, and it always detects the presence of filament. But this is a temporary solution.

Also in the new version, the felt coupling has been completely replaced; it's better and easier to print. I will not list all the changes, as they are, so to speak, "cosmetic edits", but they make improvements in almost every aspect. The first and second models are almost incompatible in terms of components. There are also a number of spring mounting holes added to the rack to adjust the tension depending on the properties of the spring itself and the required coil braking force.
