Filament clip, secure, safe for drying, updated to v3.2

Uploaded v3.2 version;

Fine-tuned; parameters and slicing are set, can be directly sent to print from mobile phone

Regular version and short version are uploaded together, everyone can choose according to their needs

Generally, the regular version is sufficient; the short version is only for newly opened full spools of filament, to facilitate automatic rolling during drying in the AMS

Tolerances have been adjusted, so theoretically, the feel of the filament feeding hole and the nut screw should be slightly dampened, neither too loose nor too tight. If it feels tight, moving it back and forth a few times should resolve it. If it's still tight, it is recommended to calibrate your machine or filament sinkage rate

Finally, please choose the threading method you find most convenient:

Increased height of the central stud for easier operation

Added holes for more flexible usage

I have used several filament clips before, all of which would experience thermal creep due to prolonged heating and drying, causing the filament to unravel inside the forced-air drying oven, AMS2pro, and AMSHT

Upon investigation, all current filament clips utilize the elastic deformation of the material to grip the filament, which is simple and convenient

However, the problem that arises is that during prolonged heating and drying, the elastically deformed parts will adapt and deform due to thermal creep, gradually reducing or even losing their elasticity, which may cause the filament to slip out and unravel inside the drying equipment

After trying several models and finding them unsatisfactory, I simply designed my own

This clip uses threads to connect and secure two components, gripping the filament by friction. Even when heated, it will only clamp tighter due to thermal expansion

Its design purpose is to prevent loosening during prolonged heating, while being compatible with various drying boxes such as AMS2pro and AMSHT. The clip body does not need to be fixed on the filament spool, and the filament does not need to extend beyond the spool

After testing it myself and finding it feasible, I uploaded it for friends who have encountered similar problems to use

Differences between the two versions:

The v1 version is taller, making it easier to operate;

The v2 version is shorter, and when used on full filament spools with height restrictions, it will not interfere with the AMS's automatic rotation during drying
