Description
Handwheel of the band saw blade tensioner FDB SG409.
At the hardware store, you need to buy a DIN931 M8x100 bolt and extend the thread with a die to the required length (same as on the broken screw). This bolt needs to be inserted into the 3D-printed handwheel, and the bolt head in the recess of the handwheel should be filled with epoxy resin.
On the 3D model, a thin partition is made in the recess for the bolt head so that the part can be printed without supports. This partition needs to be removed (drilled out or cut out with a thin knife).
