About this 3D model

Seal PTFE tubes while the filament is not in use, keep it dry in the drybox, with few cm filament kept outside of the tube you can easily pull it out, no need to open the drybox to roll the spool. Friction fit. For better user experience I suggest using TPU to print. Material: TPU Support: No Layer height: 0.2 Infill: 100%
