- Wearing a mask for any amount of time can be painful on the ears. In this DIY tutorial video, Milo shows how to create resin ear savers using a Mold Star 20T silicone mold and Smooth-Cast 65D casting resin.
The 3D print file for these ear savers can be found at: www.thingiverse.com/thing:432...

Project Goals:
Provide long term relief to your ears when wearing masks
Resin needs to be durable and semi-rigid
Create multiple castings quickly and easily
For this project, a master pattern was 3D printed. Mold Star 20T silicone is mixed and poured over the pattern to create a flexible mold. Smooth-Cast 65D semi rigid resin is then mixed and poured into the mold cavities to create multiple ear savers.
Mold Star™ 20T is an easy to use Shore 20A translucent platinum silicone that is mixed 1A:1B by volume (no weighing scale necessary). It features a relatively low viscosity and vacuum degassing is not required for most applications. Pot life is 6 minutes and cure time is 30 minutes at room temperature. www.smooth-on.com/products/mo...
Smooth-Cast™ 65D semi-rigid urethane casting resin cures quickly to a semi-rigid plastic that offers excellent impact resistance. This plastic is easy-to-use (mix ratio is 1A:1B by volume) and has low viscosities for minimal bubble entrapment. Vibrant colors are possible by adding SO-Strong™, UVO™ or Ignite™ color pigments. www.smooth-on.com/products/sm...

I have been working on perfecting ear saver straps for about 3 weeks now. I have so many failed molds because I started with straps that are easy to 3D print, rather than designs that work best with resin. My original molds have fallen short for a few reasons - but one key reason was that they were so thin that they didn't have enough mass to function well (using either 65D, which cures quick but needs mass to prevent it from stretching to break point, or Task 5, which was way too brittle). I have 4 failed gang molds which turn out either too thick to be practical or too thin to be wearable. This design ought to address those problems. I also love the idea of printing a mold box instead of trying to make up a gang-mold of individually-printed parts.
Nice work! I may start making ear saver straps again using this print!
Thanks for watching, and thanks for the input!
Hi. How can we buy one piece for apply on mould. We are in Colombia country
Great idea, you guys are amazing! Always needed when you include the costs. Thanks
Glad you liked it!
Good idea
This mold box print is 280 x 280, which is bigger than a lot of 3D printer beds (including mine, an Ender 3 which maxes out at 220 x 220). Can you share the original .stl file for just the ear saver, or better yet, a gang mold box that will fit in 220 x 220 dimensions?
We are currently uploading a smaller file to our Thingiverse page: www.thingiverse.com/SmoothOnCAD/about
@@smoothon Beautiful! It looks like this will fit my printer perfectly. I'm printing it up now. Thanks for your help!
What printer did the original large print come from? I have never seen one with a bed that large.
@@smoothon Will it be possible to make the file with only 5? I have a Qidi Pro and it won't fit on my bed. I really want to do this project pls.
Milo, how do I make it from the 3D to mold? Should I hire a company to do it?
I have watched your other video for the making of face shield. Can you upload a file for a mold box for multiple straps on one mold rather than the single print
@Smooth-On You need to check the file for this mold box. When I tried to use it there were no bottom layers. It just tried to print the walls and that's it. Looking at it in layer view there were no center layers until the part for the model for the straps to be made
We reviewed the file and all seemed correct.
What kind of 3d print material or printer is used to make such a smooth mold? I had a mold made for a project and it was not completely smooth like that is
Can you pls do a indestructible dog toy? I am keen as to make my own but would not know what products to use for the mould or the cast..
Greetings Milo
how long it takes to print it?
Which software to use for 3d Modling?
Great demo! I'd love to do some silicone casting with 3D printed molds, let me know if Smooth-On is interested in sponsored content :D
Can you contact us here? www.smooth-on.com/page/contact/
@@smoothon Will do, thanks!
hey there , out of curiosity can i pour silicone over glass to make a mold ?
You can, but you will need a release such as Ease Release 200.
Will oomoo 25 work in place of snooth on 20? I would like to make these for my local grocery store
You could use OOMOO for this, but we recommend using Ease Release 200 on the models.

I can't understand the difference between Mold release and ease release spray.
They are used interchangeably in this case.
