List the steps of making your product. For each step go to Insert > Template and search for "Step"
Using suitable measuring tools, take the measures where your item will fit into the screwdriver.
3D model the grip to dimensions and shape you need.
Split your grip 3D model and create a cavity around each part. Those cavities will be machined on machinable wax and used to create the silicone mold.
Using the CNC machine, mill the mold model on machinable wax. Note that fine finish will produce better mold.
Mix the silicone by weight or by volume, and pour into the wax model. Make sure to mix and not to exceed pot life. Wait silicone to cure.
Place the broken part into the silicone mold. Make sure that all measures are right.
Tight silicone mold parts between wood pieces. Mix the resin as per the datasheet and pour into the silicone mold.
Wait for the resin to fully cure, and then remove the silicone mold. You have a new grip and screwdriver is back to life!

Further Work & Recommendations
[edit | edit source]▶ Help!
What's next? Any recommendations?
- Instead of resin, hard silicone could be used for casting. It will provide a smoother and a better grip.
- It is possible to make the silicone mold using 3D printing.
