Any reason not to use wing nuts for the adjustable parts so you can resize without the need for a wrench?

Comments deleted.

only thing you have to ever change is infill - 50% for practical things less for non practical things (practical in this case = tool vs non tool)

Been a few since I printed but with 90% serenity I would say 1 print per object on this one

Thank you very much for the quick answer!
Do you still remember the print settings you used?

Hey, do I need to print every part only once?
I've got a problem seeing it because most of the parts look so similar and I want to get my printbed full, so I don't have to start it every three hours.
And how much infill would you recommend? Do you think 15% would be enough?
And by the way, thank you for the great idea !!!

What all is required other than the printed parts?

Something I thought of while watching your video -- maybe an ABS/Nylon-printable piece that attaches onto an electric screwdriver to rotate the bottle might be helpful for the thermal cycling process.

The irony here is you are recycling glass bottles and yet you waste so much water leaving the tap running. I guess you never lived in a place where potable water was scarce and what you had in your cistern was all you had. To me, to see all that water go down the drain, it is profoundly disturbing.

Note that my hippy parents had a similar device but you would use a candle and an ice cube to fracture the bottle, and emery powder to finish it off. Worked great.

are you able to drink from the glass or is it too sharp still?

You have to grind the edges, easiest is by hand on some sandpaper you have laying flat. Doesn't take too long, and then you can easily drink from them.

Hi there.
I have just printed out the plastic to make one of these and wondered if you could let me know how long the screwed rods are on your original. I will post a picture of the finished article - just waiting for bearings.

its really industrial and heavy duty, and wastefull resource wise speaking I just printed it and now im going to assemble, hope it likes my glass cutter.

thanks for the design

It would be so cool to be able to do this (cut bottles).
