Unfortunately, spammers took over the site and I just didn’t have the time needed to manage it all. 🙁

@beltran sorry for such a late reply. I’ve tried multiple times to clean the database, but the spammers really did a number on it and I don’t have an original backup. I’ve added the source code to https://github.com/robksawyer/preciousplasticwiki and if you have a host, I can point the DNS to it. Just send me an email: team[-AT-]preciousplasticwiki.com.

@lyricalpolymath I currently have it running on Heroku and I was messing around with scaling down the dynos to see if it’d still work. Mediawiki is a memory hog. It should be back up now. In order to really getting it running well, the cost is about $59/month 🙁

Hosting on another server would be a great. Hopefully it’s not a huge pain to do so considering I’ve added quite a few addons and configuration updates to the current install. How would you prefer me pass along the data dump?

@uaneme I’m guessing you added those details? 🙂 If so, thanks! I added the Precious Plastics machines to Thingiverse before I was aware of their terms. I need to look into this more.

Related to the lego bricks, I’ve made small silicone molds using this technique. It works great. Just build four walls of bricks and use Plastilina (non sulphur) clay to fill cracks on the inside.

@redgurrillia Great idea! I definitely think the machines can be optimized in a way that the parts are interchangeable. It’ll be up to us to document struggles during builds and then getting the right people in place to ensure that CAD models are updated and this documentation is consolidated. I could see certain committees (or task forces) being established that would manage such.

@ismaelgonzalez I’ve also been playing around with a theoretical shop. Some folks just aren’t able to weld and access the required labor or parts. And this is a problem that needs solving. I’ll be starting in the US first as it’s the easiest for me to work out kinks. Also, I will definitely share the struggles as I approach them.

Lastly, from the tone of your statement, I perceived that you may have some reservations against making this a business. And I just wanted to say that I don’t see any issue with this. I would like to hear other opinions on the topic.

I actually would 100% support a Precious Plastic producing component or machine business. It’d be great to have more businesses that are built on recycling. And also, more businesses run by people with good ethics and values (That’s probably you considering you’re hanging out in this forum.). Charge fair prices, pay fair wages, source locally when possible, don’t get greedy and make people happy. That’s just off the top of my head and I’m no business advisor, but if you do all of those, I’d be more than happy to support your business. Maybe we could even connect and somehow become distributors for various parts or certain zones of the planet to ensure that we use less energy and are able to charge folks less. 😉

@redgurrillia Would you mind starting this page (CAD Overview?)? I could use some help testing to ensure that folks are able to add items. Once it’s complete, I’ll add it to the sidebar under the Production section (unless you have a better idea).

@enviro Thanks!

I wanted to let everyone know that if you recently tried to create an account on the Precious Plastic Wiki, please try again. We mistakingly had account creation and editing turned off in the settings.

And lastly, the team is looking forward to your contributions.

@uaneme

The Precious Plastic Wiki is very much a single effort on my part to consolidate and organize the information in the forums. Note: I like forums for conversation and collecting spontaneous ideas, but I find them hard to navigate when it comes to finding specific information.

As for the link to the forum from preciousplastic.com, I agree. It was difficult for me to find the forum and I consistently have issues trying to re-find it. +1

Can you tell me what kind of error you received when you tried to sign up? I’ve been upgrading and adding some new extensions and templates lately. It may have been when an update occurred.

I just realized that I had editing and account creation turned off in the settings. Duh. This has been updated. You can now create and edit items on the wiki.

Thanks for the detail. I’ll update the matrix. Note: If you have done more tests and have numbers, please don’t hesitate to add them to the wiki. You should be able to login and edit the page.

@simonm Any further improvements to the shredder? Pedal power is brilliant.

@xxxolivierxxx Thanks for the price estimates. I’ve added these to the wiki. See http://www.preciousplasticwiki.com/index.php?title=Definitive_Motor_Guide#Estimating_Costs

@anyone have more? Feel free to add them. These estimates will definitely help folks that are building machines for bidded projects or on a donation basis.

@lyricalpolymath and everyone else that contributed, this is great. I wanted to let you know that I’ve wikified the guide over at Precious Plastic Wiki: Definitive Motor Guide.

I think the Google doc was great, but the wiki just seems a bit more organized. Everyone should be able to sign up and continue editing. Let me know if you have any concerns or issues.

@uaneme Added FreeCAD to the wiki. Thanks! Feel free to create an account and start editing.

Everyone should have the ability to add and edit items there. That’s the reason I started it. Let’s consolidate and organize the ideas from the forums there.

I’m currently trying to figure out more details related to motors (which work best) for the extrusion machine. And I could use your help. There’s now a table on the extrusion machine page in the wiki just for collecting these.

Ping [email protected] if you have any issues.

Let’s get some real info about plastics together. I see each plastic page (ex. http://preciousplasticwiki.herokuapp.com/index.php?title=Pet) having it’s own section on melting temps, restrictions, etc.

I thought it’d be great to consolidate and organize this info on the wiki. So I added a Mold section and used most of the info found in this post. Feel free to start adding more content.

http://preciousplasticwiki.herokuapp.com/index.php?title=Mold-design

I also went ahead and started a group on Thingiverse for Precious Plastic. Not sure what the process for joining is, yet. I wish I could just make it public, but not quite sure how. Maybe you’re able to submit a join request or something. Or, hopefully it is public. Check it out at http://www.thingiverse.com/groups/precious-plastic

It would be good to start some kind of spreadsheet (or a wiki page) of motors that work. I’m sure this is going to be something that other folks struggle with.

I almost seeing each machine having its own wiki. Similar to what the folks over at Shapeoko have setup for their machine. See http://www.shapeoko.com/wiki/. Something like this would allow people to add content for the specific plastic machines.

I was just about to recommend this.

And then I read further. Instead of one broad machine development category, name the four (each machine) top level topics as follows.

Machine Development – Extrusion
Machine Development – Shedder

I rebuilt most of the extrusion machine using US standard sizes.

You can find the new model at http://a360.co/1ZCPfRk.

@keesdeligt

Until I can figure out how to share the entire project, I’ve added links directly to the machines above.

I’m working on more suitable conversions (for the Extrusion machine) in the spreadsheet below as well.

I’ve simply created a project in Autocad Fusion 360, uploaded the models and converted their units to inches. However, I’m pretty sure in order to really meet standard US sizes, we’re going to need to rebuild some parts of the models.

UPDATE: New links below.
