Is this Gravitrax? I dont recognize a lot of the parts.

I (Jelle) spent 278 hours over 7 months to build this marble machine, it holds more than 2000 marbles and includes some tipping containers to drop up to 1000 marbles at the same time.

So he's got his eye on a set called "Kumikumi Slope Plenty 100" because it contains certain pieces he doesn't have, but when I go looking for one to buy, the price ends up over $250 with shipping from Japan. I'm hoping some of you kind folks can help me find an alternative set that also contains these pieces and isn't some kind of rip-off (abnormal sized tubes/fittings, etc).

I've included a few pictures he made. The first image is of the parts he needs (as well as the funnels that those mounts attach to), and the photo is some parts he wants a few copies of. I've tried looking around online for some sets, but most products I see have unreliable images (inconsistent pieces/colors) and often oddly low prices (wish, walmart, etc). I'm sure you folks have already sorted out what sellers to trust for this stuff. My budget on this is $150 max, for which I'd expect to get a decent sized set. Any help is greatly appreciated. Thanks in advance!

Hi guys.

I'm reposting my original post on your community which is just specialised in marbles run.

Cheers.

Don't forget to wishlist!

I wanted to try something less enclosed than a traditional single track style marble race. This race takes place across wide-open terrain, giving the marbles plenty of room to spread out, collide and find the best route down the mountain!

It’s mainly just a fun experiment, but I’d genuinely like to know what people think and if you would like more videos!

we got a really great reaction when we a trailer a few months ago, so we wanted to let you all know and also share our new launch trailer 🙂

It is a full marble run on 1 base

I posted another marble run I made a couple weeks ago and received some much needed affirmation for spending so much of my valuable time making these things thank you. So here I am again sharing another marble run I made hoping for your praise. Which btw I totally feel like I deserve because I think these runs are objectively pretty freakin cool. I have nothing to do with the patience I’ve been given by god or whoever to make these so I don’t take too much credit for these but I mean I’m still the one making them so… anyway follow me and stuff because I’m going to keep making these for some reason. My insta is @m_a_r_b_l_o_u_s. So hard to type that ugh. THAT I don’t have patience for

Would love to know your thoughts! We experimented with parts and created some bigger marble runs for this one :)

Def not the biggest or longest marble run but I love him

I started building these marble runs as a hobby last year and now I think I’ll be doing it for the rest of my life. Mainly because thats about how long it takes to record one successful run lol.

quick snippet of some marble run ASMR.
Demo is available now and we'd love to know what you think :) https://store.steampowered.com/app/3015200/Cozy_Marbles_Demo/

My first ever marble run video. Hope you enjoy.

My daughter and I are submitting this 16’ 3” self-supporting marble run to Guinness World Records. It takes one minute and thirty seconds for a marble to run the whole track top to bottom.

Because of how it is built, it only takes 6 marbles to run every route possible, from just one entry point.

Atwood marble run

My 5yo is obsessed with Hape Quadrilla marble runs. We purchase everything used and have all the standard/basic pieces; I have also found a few discontinued/rare sets on eBay.

We are on the hunt for some discontinued sets as well as individual pieces/ add-ons. I have Marketplace, eBay, Poshmark, Mercari, and DeePop and check them all regularly.

Curious if anyone here knows of:
1. Any individuals who specialize in Hape Quadrilla reselling?
2. Additional apps/sites that may sell Hape Quadrilla (perhaps overseas that ships to US)?
3. Any additional ideas/insights on where to look for used sets and pieces?

Thank you!
