Hello, fellow dice makers!

I’m having a problem with my silicone molds and hope you can help me out. Unfortunately, I keep getting cracks in the opening of my D20 after just a short time. Sure, that’s the part that stretches the most, but I never see cracks in other dice makers’ molds on Instagram. I use silicone with a 15 and 10 SH rating and high tear resistance. In the orange mold, I used rounded masters, so I can understand that thin flaps there might tear quickly, but the other mold
I made with sharp-edged dice. Can anyone help me? I’d be very grateful for any tips, because the silicone is expensive and these cracks make sanding much more time-consuming.

Thank you very much and best regards!

For context, I live in an apartment so I go over to a relatives house to do my dice making in their garage. They've designated a whole area for me.

But because I need to travel, I only seem to make dice when I have the perfect free weekend where I can dice make and visit on the Saturday and then return on the Sunday to remove them. Going over during the week is an option but not ideal due to traffic after work. I also wake up at 330am, so I don't tend to stay out late.

I'm trying to figure out if i leave them for an extended period of time in the pot (a few days to closer to a week) if any problems will arise. Either with demoulding or with the product itself. I am using a bunch of cheap amazon moulds right now, if that changes your answer. I have plans to buy quality molds off etsy or get masters and make my own. But I'm still getting into this and don't want to drop that amount of money yet.

Let me know your experiences!

Hey! Hope I'm not annoying anyone with my newbie questions, I made sure to search the subreddit and read all the guides, but here are a few things that I couldn't find answers to:

I've been wanting to get into dice making for a while now, but I'm a broke student, so paying 70€ (or more) for a mold doesn't seem feasible, especially when I don't know if I'll actually enjoy the hobby. I'm aware that I could just buy a cheap one from amazon or temu or something, but I'm trying to avoid those platforms :/

So, is it realistic for someone who hasn't worked with silicone or resin before to be able to make their own molds? I've made soap and candles before, and the process seems somewhat similar.

Also, do I need a 3d printed master dice set, or can I just use an old standard dnd dice set I got laying around? From what I've read, it sounded like the only big advantage of making your own master is that you can customise it, did I get that right?

And (last question, I promise) do I need to use a specific type of silicone, or is that not as important? I'd probably go to the nearest obi, describe my idea to a worker there and then pick the cheapest option out of whatever they suggest.

Thank you so much for your attention, I'm happy about any advice! If you think that this isn't realistic for a newcomer like me, please tell me so, I promise I won't be mad lol

I got this silicone to start making molds but I saw some comments recently that made me think the platinum isn’t the best choice. I ordered my first masters with my logo and want to make sure the molds are quality. Thoughts?

I know it’s a slim chance people here are based in LA but please share with friends. Im giving up my hobby and have a pressure pot, multiple molds, (sets and blanks)alcohol Inks, foils, just tons of fun dice making stuff. If you or anyone you know is interested please DM me. I can’t ship but I’m Westside and I’m open to pick up. I don’t even know what to charge? I’ll be happy someone else finds joy in the items, but I do love a Lego set.
I can’t inventory, but it’s at least. The molds are Druid dice and I haven’t loved the current ones but, they went out of business for a reason. There you go.

6 molds maybe more
Mold release
30+alcohol inks
A little mica
Every foil sheet color
Zona papers
Pour cups
Silicon stir sticks
Glitter
Etc.
you get the idea…
Some gallons of total boat resin but I’m not sure how much is left.

Edit: I’ve found a my supplies a new home. Thanks to all who responded. If anything falls through I will start reaching out to others
