Attached you can find the CNC-files I created based on the 3D files provided by Materialise.
(https://www.materialise.com/en/hands-free-door-opener/technical-information)

Download the files, CNC cut your aluminium mould and add required screws to close the mould.

Once you injected your parts with your injection machine, you can assemble the product.

You'll need:
- The two injected parts
- 2x M4 screws and Nuts
- 1x bike tube for in between

You can find more instructions for assembly here:

Do less harm, use your arm :)

Oh, and If you prefer to buy the mould, you can order it from me on the bazar:
