This is a replacement sliding ‘handle’ for a Primo (ALDI) bread slicing machine. But I will include the FreeCAD design files in case you want to adjust it for your machine.

The model is designed to be printed without supports, as shown in the profile I shared. Some areas have slight overhangs, but they should be small enough to print without issues. 

I will give the area with the spikes a coating of a food safe varnish to be extra safe. I have also blunted the spikes somewhat, to avoid them breaking off end ending up in the food.
