This is a remix of Gzumwalt's Marblevator Mini Seesaw Edition track. I was having problems with the arches under the track not printing correctly and breaking the track supports off of the print, ruining it. This is a tested model where all of those arches are removed and replaced with 90 degree angles. This fixed the problem on my printer. Have fun!
This is a long print (4 hours), but it's worth it in the end when you put the Marblevator together and watch it work!
After printing, you may need to sand some parts of the track so that they fit into the other pieces of the Marblevator. that's about it for post printing.
This was designed using Tinkercad.
