Modification of the original by Locke_Ride here: https://www.thingiverse.com/thing:5145133
The water bottle mounting holes on my Lectric XP 2.0 ST are spaced 68mm apart rather than the standard 64mm. This means that the original holder above would not fit. This modified version just adds another 4mm to the width to allow it to fit.
I don't know if other Lectric bike models have the same non-standard spacing. Comment with your findings.
I had to slightly drill out the holes on the finished print to get the M5 bolts to pass through easily. Ideally I'd further modify this print to take that into account, but for now it's an easy post-print fix.
You will need longer M5 bolts than the ones that come on the bike in order to attach this.
