With these 3d printable models, you can make your own garden tools in the absence of their handles. The handles will be recycled from the disposable razor blades you use, to prevent them from generating waste.
The different 4 models (paddle, rake, small shovel, and large shovel) have a hole designed to insert the end of the razor there (removing the blade first). This hole is designed for conventional blades such as Gillette's.
To join both pieces (the handle and the printed part) you just have to insert a little silicone/glue into the hole, insert the end of the blade handle and finish filling with silicone or glue.
3D PRINTING SETTINGS The different printed parts are designed in such a way that they do not need support.
I recommend a minimum infill of 20% and a layer height of approximately 0.16mm.
You can print them in the PLA color that you like the most and even change the color for each of the tools.
