PC4-M10 replacement (4mm PTFE holder); DLP project

PC4-M10 replacement for 4MM PTFE tube. Strange, but works ;)
Project for DLP printer. On FDM - it may works.

edit #1
I have added second, larger handle (Zamykadlo_2A, _2B). It works better ;) Printed with ASA.

edit #2
I have added third version (Zamykadlo_3A, _3B). Printed with ABS.
