Bosch Drilcase Lock

The lockclips on Bosch cases happen to break after years of use. Therefore I needed a replacement lock for the case of the Bosch SDS Drill. The lock could be used for other things too of course.

How I Designed This

Design

I designed this in OnShape but created a sketch with pencil on paper first. Dimensions are based on what I thought should work out.

Parts and steps

Pins

To assemble this lock you need to make pins out of 3mm screws, just saw the top off and make a small incision on one side of the pin to be able to screw them into the parts.
Needed for one lock is a four 3mm screws cut-off to a length of two times 6mm and two times 10mm.

Blocks

The blocks can be sliced from 7mm for printing without support material. After printing cleanup both parts of the block and apply a tiny bit of glue before assembling.

Holes

Drill the holes to 3mm. You need four screws, rings and nuts to mount this onto the case. See the pictures for the endresult.

Happy drilling!
