A1 Mini filament tangle control

This mod reduces the likelihood of filament tangle that occurs when the print head rapidly drops from a high height to the build plate level. This happened to me several times when the filament in the external reel would rap around the spool when the print head drop occured. This mod attaches as shown to the vertical z axis pillar and the filament is fed into it from the rear and through a PTFE tube up to the PTFE tube leading to the print head. When the print head descends the filament no longer can wrap around the filament spool. I have used this successfully for many months. As shown, there is an attachment hole where you can use the screw in the base of the Z axis pillar to secure it but I found over time this isn't necessary, it just stays in place as it fits snug around and under the right rear of the printer. I printed it with PLA, 2 wall loops, 5 top shell layers, 3 bottom shell layers, 15% infill using gyroid, and minimal support is required keeping the total weight under
