Description

Boost Me (for free)

There are 20+ parts in this print that all fit together and print without support. If you appreciate this model as much as I do, please share your boost with me.

This model took me way too long to make. For those interested, it was made in Fusion360. It made me lose my marbles! This print requires no AMS and no supports by design.

I only have printed marbles. I acknowledge they sometimes bounce and go flying, but that's part of the fun! (definitely not an excuse) . One user has reported better reliability by scaling the entire print by 4%, so you may want to consider that.

I recommend using 8mm steel balls if you have them. You can choose to glue pieces or shove some leftover brim pieces (from the print) in the gaps to secure the towers.

All the hinges are made with a piece of 1.75 mm filament. This includes the ToppleTower™, the mechanism in the base, and the seesaw in the upper tower. So **3 hinges**.

This piece is printed with **100% infill** to add weight to the bottom (look at the preview, it is hollow in the top). If your tower doesn't topple, try reducing the infill percentage to 50% and go from there.

Really great model, I would prefer it without glueing but it is a really great work and deserves a win! Good luck!

The designer has replied

@Zwamdurkel

Thanks! you definitely do not need to glue it if you don't want to. I have not glued mine. I just stuffed a piece of leftover PLA brim between the topple tower to lock it in place and that's good enough for me. The other parts stay put during normal use.

Replying to @Zwamdurkel :

I understand but mine has some friction which pushed the loose towers up when pressing the button. Also the small parts should be more snug in my opinion to work without glue. The brim solution is possible but I'm an Engineer how could I do something like that ;-)

@Zwamdurkel

Replying to @ohrenstoepsel :

How many mm gap do you usually leave on your models for 1. friction fit and 2. sliding fit? I've used 0.2 offset on all sides for this model. I know that the printers can do some crazy stuff (I've gotten 0.06 to work in the past, a bit tight). But I didn't want to risk it for this one, so everything would fit first try. I don't like wasting plastic. I hope you understand and I will try to make it tighter for the next model. -P.S. I'll soon be joining the engineer club, just a few months of uni left.

I love seeing the colors that everyone uses! Thanks for printing.

Great little print, very well designed. Steel ball bearings tend to want to bounce out, but after printing the entire model 4% larger, it seemed to have remedied that. Additionally, I made two changes. First, I added fuzzy skin to the pointed roofs to look more realistic, and second I added a little flange to the bottom of the button/plunger to prevent it from falling out. I’ve incouded a pic of that as well. I would strongly recommend making that change/update.

The designer has replied

@Zwamdurkel

I never even considered installing the plunger from below. I will try adding it when I have some time. Thanks for printing!

@Zwamdurkel

Also, I totally wouldn't mind if you add your 4% larger version as a print profile, but I'm not sure how MakerWorld guidelines classify that.

Worked great! Balls get disconnected from the table, but it is expected on bedslingers, coreXY works better for this.

Thanks for sharing your picture!

So I printed this not having much hopes, but it actually works! I glued all the parts together. My son is having fun with it for like an hour already. I bought 20 8 mm steel ball bearings in local shop and 20 is enough for some fun as 'topple tower' sometimes throws balls around - part of the fun as you said. I use Fusion myself and I highly respect your effort doing this in Fusion, I almost feel your pain buddy. Thank you, hope you win the competition, you deserve it.

@Zwamdurkel

Thank you for understanding my pain with Fusion. It would take a good minute to compute any changes towards the end of the project. Maybe it's time to learn Blender properly...

This ball track is truly magnificent, and the craftsmanship is evident 😊 The print was largely flawless without supports. Only for the balls did I have to activate supports and significantly reduce the print speed, as they kept jumping off the print bed beforehand. However, this is not due to the print profile, but to the movable print bed of my A1 mini

Thank you for sharing the first picture! Yes, printing spheres is hard on a 3D printer. I'm glad you made it work.

This was a fantastic build! Thanks for this one :) ... Really enjoyed it, mainly built for my girls, but, my wife has absconded with it, I believe it is now hers! hah hah ... not sure if I'm allowed to do this or not, but, here's a little vid I took of it over on my insta: https://www.instagram.com/reel/DEOxCMzTinD/?utm_source=ig_web_copy_link&;igsh=MzRlODBiNWFlZA==
