Great Model, a blind version would be great.
The two mm shoul
d remainso the filament doesn't get pushed back but the end of the cennector is closed

These turnd out great and work really well. I had to modify them for a larger magent. Printed in ASA in a few minutes. Create work to the maker.

Hi @jurassic73 , I am currently working on a project where I use your twistlock connectors for my filament boxes. For this use case I would like to design end caps based on your design (a little different to the existing remix of your design)
Would you perhaps also share the step files of your models, or at least of the female parts, with us? This would help me so much!

@Glindmeister I've added STEP files. Happy modeling!

I use them for my filament end holder — great idea! I had to print them at 103% to get the thread of the Bowden connectors to fit into the hole.”

had a touch of trouble getting the magnets in, but managed to force them in with pliers.

Very essential for mmu3 users...

Came out great! 3mm magnets fit perfectly. Nice and snug, didn't need glue. The slide action is very satisfying. Excited to get them hooked up to my setup

I just bought a Creality Hi Combo, which includes their CFS unit. My plan is to build a Lack enclosure, with the CFS and single spool holder on the top of the enclosure, with both PTFE tubes going into the table. Inside, I'll have a mounted PTFE tube, which will be attached to the print head. This connector looks perfect as the in-between, for connecting either the single spool or CFS unit to the printhead quickly and easily.

No issues with the automated loading and unloading?

@DennisMckinn_3312613 None that I've heard of from other users(see comments). There are tapers built in to help avoid any hangups.

@jurassic73 Awesome to hear. Thank you. I'll post the make once it's done.

Using it to extend the PTFE tubing to the drybox. But I can easily remove it if I want to use the normal spool holder.
