Marble track - motorized lift - v3 - stand-alone height adjustable Gravitrax compatible!

thingiverse

Here is the fully revised version of the motorized lift for marble tracks! This time around, I've created a standalone model with its own base, rather than relying on my basic six-exit tile design. The previous model had issues printing the connection part to the six-exit tile, so this new design addresses that problem (see comments). Another improvement is the connection pins. Version 1 had pins printed directly onto the extender parts, which caused them to break due to layer orientation. This version uses separate pins that are inserted into the connection holes of the extenders, creating a much more robust construction. I've also improved the inputs and outputs of the lift. The balls now flow in and out smoothly, with fewer instances of balls not being picked up by the coil part. Finally, this new design is better printable than ever before - no supports are needed!

Update 15th of November I've updated the lengths of the followers and coils to have height differences of 15, 30, 60, 90 mm. The exits are already 30mm in height, and the new input piece is also 30mm in height. This design promotes modular construction of a tall lift. The parts are now named as version 3. Version 2 is still provided but as a zip file. Update 28th of October For those who had trouble finding the correct motor, I've added a link to the shop where I purchased my motors (30rpm, 6V). https://a.aliexpress.com/_B0L3B5 Update 22nd of September Thanks to Lucas Moraes Abarca for suggesting an input piece that can feed balls back into the lift and exit through a higher-level exit. This design allows for multiple entry points and one (or more) exit points. The Input part allows the lift to be used with multiple entry points and one (or more) exit points. Update 5th of September Version 2 is released! Please consider supporting my design efforts, thanks! Update 11th of Augustus Due to some fragile elements in the construction, I've decided to create version 2 of the lift. Still working on the design and prototyping. If you decide to print my lift, please wait for version 2. Update 21st of June: Major update for final design. Changed the ball input to prevent blocking, added an inner hole to the pins which connect the separate parts to make them stronger. The whole structure now needs to be built at the same level in order to close the structure with the top ring and improve stability. The exits can be at different heights by simply switching the parts to get the desired height. The motor part is fitted for motor type: * Voltage: DC 6V * Material: Metal * Model: N20 * Revolving Speed: 30 RPM * Total Length: 36mm * Motor Size: 12mm(diameter)*26mm(height) * Shaft Size: 3mm(diameter)*10mm(length) The whole thing can now run autonomously without jamming. Update 20th June; Just received the motor, it works, but I should make some minor changes to the design to make it work autonomously. So wait a little while with printing this thing until the next update! Update 2020 apr 24; Motor rotor and coil bottom are now separate parts. I still need to receive and test it with the motor, but already worked through three prototypes to be able to lift the balls properly.
