Elastic Cord Wrap Ends

[MetalDesigner]

I end up with filament spools with just a few wraps left on them, so it is nice to have little items to print.



Use what you have ... ... and Brenda has elastic hair ties which make nice cord wraps when used with these 3D-Printed ends.



Also work to hold other items ...



The .STL files for 3D printing are on GrabCAD

Nothing fancy... but they work for what I need.

... CHEERS!!

Brilliant! Much more convenient than Velcro tie. I use the big brother tarp ball type ones for everything. But I've been wishing there was a small version. Now if I only had a 3D printer.......

[Christophe Mineau]

Yes , would say the same, brillant !
For those who don't 3D print, I wonder if this couldn't be done with simple buttons, big buttons from a coat for example, the kind with a loop under.

Video Talks about using Recycled Plastic to make Plastic Molded items & 3D-Printed items

Someone asked me if there were any machines out there that could chew up and recycle plastic items to make 3D-Printing filament.

CHEERS!!

When it comes to talking about the process of making the filament for 3d printing DIY is possible however a lot of knowledge in recycling plastics is required. most production type recycling centers start out with a prewash then sorting, cutting then wash and dry which will cause a reduction and thickening in size due to the heat involved then pelleting, mixing,extruding cooling winding and so forth.
One of the things a DIYer would be doing would he would start out with all like plastics this would negate the sorting operation.
Our machines would be a lot smaller as well but one very important thing is a near steam washing and rinsing the hotter the better hot air drying will further cause reduction and thickening.
For the grinding operation think of a machine constructed much like an industrial sausage grinder but with 2 sets of counter rotating blades for the string extrusion machine it could be another similar machine as the sausage grinder but with a tapered screw but with a near solid rubber packing that it must turn through which helps to force the plastic pellets to a high pressure to feed a piston pump forcing the now heated liquid plastic through an orifice next you will need a series of pulleys to pass the filament string over to allow for cooling lastly will be a spool winding machine,
Here is a good site to help explain the process of re processing plastics

Thank you for bringing this to our attention and very apropos considering last Friday, April 22 was Earth Day 2016.

Your grabcad link is 404'd so I knocked out a quick "inspired by" design. It's printing now. Thanks for this, it's 10/10!

Thanks for updating this old post and the slicer image, Elizabeth. What is that green, unconnected line around the part? And what is the length of the part? I'll mill some out of aluminum. I don't have a 3d printer. . . . yet!

The unconnected green line is called a skirt. It's an artifact of 3d printing used to purge the nozzle that you just throw away. When I get home I'll put up the CAD file on GitHub and post a link here.
