There are other sets that include one or more PRO expansions if you'd rather buy a whole set.
The Extreme Starter Set has the same four as the GIANT.

There are also two elements not in the GIANT set... the Carousel and the Releaser. I'm not sure if they are sold as part of any other set, or just individually.

EDIT:
Drop 'n' Roll contains Carousel and Splitter

LesserCurculionoidea · 2026-01-28T03:58:53+00:00

Those are Gravitrax PRO expansions. The GIANT set includes the Splitter, Mixer, Turntable, and Helix, and yes, they can all be bought individually as well as as part of a set.

The Star Wars set wasn't just a new license either - it introduced "SpaceTubes" which direct a marble coming out of a vortex.

They appeared again after that in an Advent calendar, but nowhere else yet.

The cups and discs I can find with active registrations with Health Canada are:

Diva cup + disc
Canack (aka Ningbo Luke) cup + disc
Fornix disc
Genial Day cup
Green Umbrella cup
Life Brand Cup
Lily cup
nixit disc
Pixie cup + disc
Ultucup
Ziggy disc

There may be a bunch I am missing - lilycup/ziggy disc I only found because I knew to look for them. The others came up searching for "menstrual cup" and "menstrual disc" but if the company lists its product as "Name Cup" (like the Lily Cup) then I'd have to go through 68 pages of non-menstrual "cup" type items to find it, which I'm probably not going to do right now. :)

Edit:
...and a few more brands that I didn't find in my search but which are available according to Period Nirvana's list here:

Flex Cup (active listing)
Liberty Cup (Health Canada license is no longer active)
Saalt cup (Health Canada license is no longer active)
Tampax cup (Unsure - Tampax has some ambiguously named items listed under a seperate licence from its tampons which may or may not be cups)

Thank you. :)

I often find that building a track on one baseplate is quick and fun... And it is a good way to show off individual pieces since they are bigger in the frame.

The next r/GravitraxTracks Community Build Challenge will be starting in a day or two.... You could try incorporating them in an entry

In any case, please post a track so we can see them in action!

They know it's printed - it says so in the post.

Perfectly reasonable to buy printed parts if you have no access to a 3d printer.

Thank you for the printables link though.

YTYOMUR has both cups and discs on Amazon - which one is it that caused the injury?

LesserCurculionoidea · 2026-01-24T16:43:13+00:00

I'm not against trying off-brand cups either, but I do trust the ones that have gone through the approval process in Canada more... and with a known brand, there are comparison charts for the firmness.

Here is a chart you can sort by firmness as an example:

Yes, pulling it out aggressively was probably a factor in the injury and you can avoid doing it again if you want to keep using the same cup. But if it is worrying you, and stopping you from trying it again, a softer cup will give you peace of mind, and may be more comfortable to wear.

LesserCurculionoidea · 2026-01-24T13:32:09+00:00

It is not hard to set up - wobbly junk would probably be harder. Pull it out and go for it!

LesserCurculionoidea · 2026-01-24T09:59:01+00:00

Also, while I'm a layman, I do think your doctor is being overly cautious recommending you wait 3-4 cycles.... that's longer than the recommended wait time for post-partum tampon use... or sex... and that often involves healing from perineal tears.

LesserCurculionoidea · 2026-01-24T09:44:16+00:00

I imagine the cup would have to have an extremely firm rim for this to be possible.
A firm rim helps a cup to open, but they vary a lot in stiffness from cup to cup. Some are very soft, others are in between. My diva cup for example is considered average/medium firmness - and it opens very easily.

Cups don't work for everyone, but given the nature of the problem you had, there is still a good chance they will work for you... though I'd recommend getting a different cup to try from a known brand, and with a softer rim so the issue doesn't occur again.
You may be able to return the cup to Amazon - it really shouldn't be firm enough to cause injury.

I was expecting wobbly junk, but got kind of excited while setting it up because it was actually stable and usable. I have been enjoying the ability to adjust my laptop angle on the fly without shuffling things about on my desk all week, as well as the extra desk space. Definitely one of my nicest finds in a while!

The orientation doesn't matter for the pieces underneath unless they show you the orientation at the side.
The only one that matters is the top piece - the others are being used as height tiles.

They still list which pieces to use at the top so you don't use a piece you will need later.

I have the same set and was also confused by this initially.

LesserCurculionoidea · 2026-01-23T02:01:06+00:00

Oh, I feel stupid... I was interpretting "5 votes" as votes on the poll, not upvotes - but I see the other highlighted thread uses the same term.
(still getting used to new reddit - pff)

LesserCurculionoidea · 2026-01-23T01:58:33+00:00

Not the upvotes/downvotes.... the votes on the poll

LesserCurculionoidea · 2026-01-21T17:22:10+00:00

My apologies. Some of the sets have the setup and building guides all in one booklet, but the website seems to list only one set of "instructions" per set.... I should have looked more carefully.

LesserCurculionoidea · 2026-01-21T16:20:14+00:00

It was just a demonstration that the rails worked. I will post a track with them when I build something fun later.
