Instructions
1. Start printing the part.
2. Screw nuts onto the ends of the PTFE tube (see parts list). If needed, cut a little material away from at the end of the tube to make it fit.
3. If your filaments do not run through easily anymore, run a 3mm drill through the end where you have the nut.
4. If you want it to be able to stand more force, put a drop of super glue on the PTFE (above the nut) and screw the nut a bit further. Then truncate the PTFE to be flush with the nut.
5. Push it into the printed part.
