I tried the (free) bucket list and triple twister Like everything with 3D printing, it required some tweaking to make it run perfectly. My printer made everything a little tight, even after the calibration. It just required some sanding or scraping. For the chain to fit, I needed an extra link to lengthen it and it worked fine. Some of the little attaching pegs broke off, but I just super glued them in. Overall, I think its an amazing design, I marvel at how somebody could engineer something like that. I will probably buy more of the designs to make.
Had a great time printing this with my son. This was our first more "advanced" 3d print and the Ender 3 v2 handled it beautifully. The only downside is that the pegs that are used to mount the modules break off easily. We ended up using epoxy to permanently attach this one build. Would love to see some type of metal rod or insert that could be used instead of printed extrusions.
Printed very well. Feel like the ball run connections should have some sort of key system to help with alignment.
Really nice model. Gave me reason to buy all the other STLs as well.
