I made this scooter stand for my tree nephews.
 

• Modular: another one can be added to the exsiting ones
• Robust: It is build to withstand kids ;)
• Steady: A big ground surface makes sure that the scooter will not fall
• Askew: Angular assembly so the handlebars of the scooter will not collide and every scooter can be taken from the stand without problems

You can glue the parts together or use the fixture part and some screws to fix everything together.

The model fits on a 200x200 bed if you turn the model around 14°

If you just need one single stand:

• Use Scooter_stand_single

If you need more than one:

• 1x Scooter_stand_left_end
• 1x Scooter_stand_right_end
• As many Scooter_stand_mid as you need
• Number of Scooter_stand_fixture = 1 + Number of Scooter_stand_mid
