Marble track - motorized lift - strut

thingiverse

With a larger builds of the motorized lift of Oostmeijer, I had the problem that the followers started to get pushed out, resulting in marbles dropping out. The same as described by Morphus2k in his very similar remix. I glued the pins into the top holes of the followers, so I can't replace the pins with larger ones, as Morphus in his remix. Therefore I created a 5 mm Ring that works as a strut and keeps the followers in place. To save space I included the pins at the top into the print. One of these added after 10cm of height gives the structure quite a lot of extra stability.
