The original mount didn't work, because BL-Smart 2 doesn't fit to the holder and adjusting it higher isn't possible. Also I made it a bit more stable in the area for the big bolt head.
To see changes compared to the original, please have a look to the screenshot I included. Now there is a little bit more space for adjustment. Included springs still don't fit.
If you need a special version, you can use the included version in STEP-format and adjust it for your use.
V2 made a minor change to holes and providing source file in STEP-format
It would be great to support me and help me to implement more improvements and features with donating my work here -> https://www.paypal.me/klauskorte
Additional version with less material and more smoothed edges. One leg shortened, because this decreased also weight and printing time.
