Food or Object Pusher
by mamclain, published
This model is a food or object --- such as paper --- pusher. This model was originally designed to replace a missing food pusher for a meat slicer; however, I have also discovered that this model can be used to help feed book pages that have been cut from the book spine into a HP automatic scanner feeder.
The rationale behind doing this is because the feeder of some automatic scanners tends to kick small paper stacks away; this item provides enough cross-sectional weight to keep the book pages or small paper stacks within reach of the feeder.

Note, if you are going to use this as a food slicer pusher you might want to consider adding small spikes to the end to help grip slippery meats.
Disclaimer, working around sharp blades is dangerous business and naturally, a plastic guard is no substitute for a metal one, please cut responsibly. Use of this item for dangerous applications is done so at your own personal risk.
You might need to scale this model to fit your printer or intened application, and reasonable scaling should produce good results.
You should probably print this with support material enabled, oherwise it will come out incorrectly
I removed my support up with a pair of wire cutters and did some smoothing with a nail file and a Rotary Tool. Be careful.
I Printed with ABS Green plastic
this model was done in scad and files are included.
This model could use some more refinement feel free to modify it if needed.
I like to run my printer slow and steady since my print deck has a tendency to dance around a bit so your configurations will vary.
