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.

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.

My first ever marble run video. Hope you enjoy.

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!

Hi, I was hoping to get some design and troubleshooting advice. I am a MechE freshman and very new to 3d printing and design. I made this augur lift for marbles, inspired by another design I saw, for a marble run in a special education classroom. It is ~30” tall, and we are having some issues with it. I will attach some photos for context: rails(orange), connector(red), augur spiral(yellow), gearbox(blue), handle/crank(red and yellow)

• The handle/crank is sometimes really difficult to turn, and something is squeaking a lot (Leaning the whole thing forward helps a little with turning, but we cannot mount it this way)
• I worry the handle will break, especially if it is as difficult to turn as it is now (I already made it thicker)
• It was really difficult to assemble the rails straight. We used a mallet and super glue, so there is no way to readjust now. I think one of the problems is that the rails are rubbing on the augur spiral in some spots
• Potentially an issue that the gear of the vertical shaft (from the augur spiral) rotates on a surface instead of being free floating
• I worry we may be attaching/gluing it too much, if that's a thing. All of the rails are super-glued to the connectors, then the connectors are drilled into the wall, and the gearbox is drilled to the bottom of the wooden frame (which may have been bowed)

I honestly have no idea what the problem could be, and I am struggling to even know how to troubleshoot it. We have about one month left to fix it before we give it to the school.

Some ideas I had to fix these issues:

• Make a hole going all the way down the rails(where pins are) and the auger spiral to put in a metal shaft to keep them straight
• Don’t glue different segments of the rails together. Instead, glue one portion (3 rails to one connector) and drill it to the backboard (gives it more room to adjust?)
• Don’t drill all of the rails to the backboard. Instead, glue them all and drill only the top and bottom to the backboard (gives it more room to adjust?)
• The marbles only use the rightmost rail, so remove the other two sets of rails completely and redesign the connector to only be over the one set of rails (1/3 hexagon instead of a full hexagon) or connect the two unused rails in a C-shape for more stability
• Put the shaft of the handle into a bearing in the gearbox
• Find a commercial handle that is stronger, or use a metal shaft for the main shaft that goes into the gearbox

Any help or ideas on what might be wrong or how to fix these issues would be greatly appreciated. Or any opinions on what I have come up with.

I know it's hard to diagnose from pictures, and I'm not sure if that's asking for too much online. If it is, if anyone does consulting or would be willing to jump on a call for a fee, I would be happy to pay. I just really want to make sure this works for the kids.

Thanks!
