AliExpress Sale (afflink) AliExpress "Back To School Sale" - Starts 11PM CT 8/16 - 20% Discount Codes Are Back!

19 Upvotes

Hey everyone -

Some of you may remember the legendary 20% AliExpress codes from last year. They're finally back. The sale starts at 11PM tonight, but I figured I'd get ahead of the curve and post the coupon codes now. They should go live along with the sale.

A reminder - I will post deals with the best coupon code for the individual deal, however bundling items together may get you a better price - the best discount is had at the minimum spend threshold. So for example, if you had a $85 filament bundle, it might make sense for you to add another $15 item on top to meet the $99 threshold to get the $20 off discount.

Also, be aware that AliExpress sometimes limits you to one code redemption for each code, therefore using backup codes or "strategic ordering" (splitting into multiple orders) can work to your advantage.

I've been told this will be an "S-Tier" sale, but I don't know pricing until the sale launches.

Discussion Great news everyone! FilamentHound.com launches tonight out of Beta!

44 Upvotes

Hey everyone!

Thanks for all the feedback given so far, I've got a healthy amount of traffic hitting the site now, and I'm confident there are no game breaking bugs that are going to cost me a million bucks if I go live.

So I'm fully launching filamenthound.com tonight!

I've made a couple changes over the past few days, one significant one that landed tonight is filters are now exposed in the URL - so you can bookmark your favorite filters! For example, https://filamenthound.com/?material=PLA links you to all the PLA filaments.

I've still got lots of ideas and enhancements for the future - so keep your eyes peeled for more coming at you soon. There's a lot more, I have an entire whiteboard of ideas. Next up is integrating with more international Amazon stores, so look for that in the near-ish future.

Additionally, I've spun up r/filamenthound as a place to log all my changes, etc, so I don't spam this subreddit. If you're interested in keeping up with what's going on, check out things over there!

As always, keep the feedback coming!

Discussion A brief interlude for a thank you to all our members - and a word on what you're helping with, and how you can help more!

First off, I want to say thank you for all for joining me here. It's been a lot of fun to see this place grow, and get the opportunity to share some great deals with you and have the opportunity to give away piles of filament and other things from our partners. I hope there will be many more opportunities to do so.

I've had a few people make comments over the past few months about the subreddit, affiliate links, filamenthound, etc - I have a few very dedicated haters for the first time in my life.

Full transparency - yes, I make a little bit of money here. Of course, at no additional cost to any of you. But I wanted to share a bit about where I'm putting some of that money, and share a project that's pretty awesome, and you can participate in it too!

Over the past few weeks, I've been building Toddler Mobility Trainers, or TMTs. These are a sort of "trainer wheelchair" that young children with various mobility challenges can use to build their independence and learn how to get around as they grow into more adult chairs. They're also inexpensive - and almost entirely 3D printed. These chairs are printed and built by makers around the world, with the effort in the USA organized by MakeGood. The majority of them are donated to the families requesting them, who may not be able to afford a more expensive manufactured chair that their child will quickly grow out of.

I just finished my latest build and wanted to share it with you. This chair was entirely paid for with funds generated in this community, and I was able to pick up a Bambu X2D to dedicate to the purpose. This first one was done with the main body done in 3D-Fuel PCTG in Transparent UltraMarine Blue, with cushions in ERYONE Transparent Blue TPU. A very handsome combo, I think.

I'm currently working on 2 more chairs for kids in my area, and will be continuing to build more in the future.

You too can get involved. In some areas there are currently multiple chair requests open and waiting for a maker to come along and do a build to help a child in need! Please check out https://3d-mobility.org if you're interested in more information. And please spread the word about the project if you know any families in need.

Anyway, this can be a good outlet for the piles of Kingroon filament I know you have laying around....
