Bosch Circular Saw Guide Rail

Guide rail for some of Bosch's circular saws. It is modeled after the original part from Bosch and fully compatible with them. The locking mechanism works well. I recommend printing it in PETG since it's more slippery than PLA. But I have done some in PLA and it works just fine.

The TPU feet are not optional, they will need to be glued on and then cut in like with a normal guide rail. I used TPU 87A which seems to work well. You could try other materials but soft TPU is nice since it is quite grippy like the original rubber.

Building instruction:

1. remove support from guide rail, this can be pretty annoying and small pliers + needle files are nice to have.
2. insert locking buttons on the bottom (they should only go in one way)
3. glue on TPU feet
4. cut off TPU feet with circular saw

While the locking mechanism worked fine in my tests, I would recommend to just epoxy the rails together if you don't really plan to use them in shorter configurations anyways. Use a straight edge for maximum precision when gluing.
