String serving tool

I have been using the original version of this tool for many years with some cheap backups which do not fulfill my expectations. So I created a modified printable version of my favorite. It can be used with plastic nuts with embedded M5 nuts or, if you prefer the weight, there is an adapter that holds an M14 nut on the outside additionally.

All .stl are enclosed in the .zip file. Note the part Winder base right has to be mirrored in slicer.

Material PLA, PETG, ABS all tested and worked fine.

First layer height 0,2mm
Layer height 0,15mm for base and axes
Layer height 0,1mm for spacers and nuts 
Use high infill, for example 80% in the base parts to gain weight.

No brims, no supports needed.

For more details see .3mf files with settings for Prusa MK4. You can simply print each of them once and you receive all the parts.

Additionally required for assembly

2 pcs. hex nut M5 DIN934
1 pc. threaded rod M5 x 93 (for plastic nut 90mm is sufficient)
1 pc. socked head screw M3 x 40 DIN912

optional
2 pcs. hex nut M14 DIN934 

Have fun and enjoy it. Feedback will be welcome.
