This model consists of three main parts:
In my case, I had 2xS, 2xM and 3xL screwdrivers, so I put these together.
Each module is available with fillets on the right/left/both or no side, so you can choose the appropriate ones for the end of your “chain”.
The individual files are included as step files and the original FreeCad file has also been uploaded, so you can tweak the design to your liking.
Printed using 10% infill, 0.20mm layer height in PLA.
The author remixed this model.
