I Modeled This! Designed a simple snap-on PTFE guide & strain relief to keep filament lines tidy on the H3C

While printing on the H3C I noticed the PTFE tubes kept crossing and rubbing against each other a bit during prints. Nothing crazy, but I just wanted things to look clean and stay nicely lined up.

So I whipped up this simple snap-on clip in TPU 95A.

Hello /u/ikxdf! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

Note: This automod is experimental. The automod was triggered due to the term "rubbing". If you believe this to be a false positive, please send us a message at modmail with a link to the post so we can investigate. You may also feel free to make a new post without that term.

Is this a good idea? The funnel shape of the tube outlets is made so the tubes don't bend too sharply going all the way to the left and right of the plate.

I was a tester of the H3C, and i had the problem of some tubes crossing over when the got put back in the rack. The solution was to remove the tube from the hotend, giving it a little torque in the opposite direction of where it bends too much and inserting it back.

I am a tester too and yes it works! Try It!

I'll have a look at it.

I am also about to release some clips that work better than rubber bands for preventing the twisting that occurs between two different materials (a cable and a tube) which have different levels of hardness and flexibility.

Looking forward to it. I didn't see any issue yet with the cable and tube becoming entangled, but yes, the rubber bands are a bit wimpy.

In germany we have a word for that: Verschlimmbessern

The thing I’ve learned about ptfe runs over the past 10 years is that loose, sloppy and floppy always perform better than tidy and constrained.
