Vespa Stella Bajaj grip adapter

thingiverse

Bar adapter for "shifty" scooters that use the same size grip on both bars. These will work with standard 22mm (7/8") grips on a scooter that has a roughly 110mm bar end to take up the space that is left when "standard" size grips are installed. There are two files, one for shorter 125mm motorcycle grips, and another for longer 135mm MTB grips which are commonly available and both grips are 22mm so you don't need to buy two sets to work with your scooter. I have only tested this on my own Bajaj Chetak scooter, I am unsure if it will fit Vespa PX or Stella scooters. There is a one-line thick support feature under the flange to facilitate the overhang of the end of the piece, you can either leave this on and it will fit very tightly to the bar, or you can very easily slice it and peel it off like in the picture. Even then my printer struggled with overhangs on TPU. Using 25% infill with triangle pattern made a good compromise with rigidity and flexibility. You could use different hardness of TPU for different results.
