Spare time takes on a whole new meaning. Tabletop Bowling includes a launch ramp, a lane that prints in 2 parts and fits snugly together and ten pins you can print in one or two colors. Use a marble for the bowling ball and get rolling.
Assembled bowling lane is approx 276mm/11in long x 65mm/2.5in wide.
Note I did not design this model. Let me know if there are issues with the model. I took the design of the bowling pins listed below and scaled it to the appropriate size.
