3DP version of the Cen-Tec Quick Click Hose

Nice one, I was just going through my comments as this model is getting attention for some reason. I've made a few attachments and I made a very similar one. https://makerworld.com/en/models/859269-40mm-cen-tec-hose-splitter-adapter

I based my model on yours, of course! I decided I needed a Y connector only occasionally, so I made it a 3-way Quick-Click so I could set it up and break it down quickly. You have helped spur my interest in learning more about 3D modeling. I've collected Centec parts and ideas from you, Making Dove, and other makers. Now I have 3 parametric Centec models in Fusion: male with vent, male without vent, and female. Next I plan to learn threading so I can make the shop vac end that comes with the Centec hoses. Hmmm ... any chance you'd share the threading parameters for this?

I'm delighted you've been inspired to learn 3D modelling. I'm not in front of my CAD computer much as I'm overwhelmed with other tasks. Re speckling the thread you measure the space between the bumps on the hose (it's a reverse thread) and the diameter you need, those dimensions are all you need for the spiral. The actual thread design was with a 30 deg undercut wall, basically a 2D triangle with fillets. I made 2 threads so I could print one upside down. (the 30 deg was so the overhang would be well-supported. If i was you i would just import my .stp files and make that an object. That's what I did with many of my other components, and what many on Maker World have done. It's not one of those things that copyright, (as its pure function) so just use it as you see fit.

That gap is huge. Two possible reasons I can think of 1. you glued the retaining ring on upside down. 2. you printed with support (everything should print without support) and the support is adding spacing. On reexamining your photo, the top ring was glued on upside down. The top housing and retaining ring fit together in a male and female clip style, sandwiching the 0 shaped spring. You dont need much glue, only add glue to the female side, to avoid gluing the 0 clip.

Thanks. "If I only had a brain." 🙄 Glue part worked out OK. I used thin, but it ran terribly. Will use thick next time.

All good. Bad hair day LOL

Applying superglue can be a bit of an art. I've found less is better for 3D prints. This print the lines work to strengthen the bond, so just applying a little bit of glue to the inside of the small ring part should be more than enough.

PS. I hope you get a usable print. I Also see you have what look like 20mm bench dog holes. I also made a bench dog vacuum hose attachment for the Cen-Tec hose you may find useful.

Oh those clips look useful. I'll get a handful of those printed too, thanks. I'll try to print again over the weekend though and be a bit more delicate with the glue this time.

Thanks for sharing the photo, looks good, hope it works for you as well as it's worked for me. I'm testing a spin welding jig so you can weld the two parts in place with friction - no glue. (I just mention it because you're printing ABS.) PETG and PLA are two soft, but my ABS version welded great. I'm new to printing my own parts and have had some issues getting ABS to stick to the plate, so the ABS spin weld is still in testing.

It's a real good design. I'm using Bambu Labs ABS GF on the PEI Textured Plate. I'm using brimming, and have slow my print right down. For first layer I print at 0.28mm @ 30mm/s. Increased my temps 5 degrees with the hotend and plate.

That looks so cool. Nice work, I'll try slowing my speed next time I print ABS Did you dry the filament first?

The odds are slim, but I'm at work and already in shit, so why not.

Heck yeah! Thank you so much!

PS I'm assuming it's a 47mm OD and hose thread is also a reverse thread, I don't know the thread pitch (space between bumps) so I just scaled the cen-tec thread to a bigger side - it may or may not fit. Generally, there is prototyping and many iterations before you get a Woking design - this one is "use at your own risk". I've uploaded the .stp file, if you click Download STL/CAD files you should see it there. when it's finished verifying. it's an Assembly, so bring it in as separate parts - and arrange intelligently.

Thanks.

Thanks for the CA tip. Your print looks so clean.
