Replacement Foot for Fellows Stacking Wire Tray.

The rubber feet that come with the Fellows stacking wire trays can dry rot and fail. Fellowes does not sell just the feet, so you’re stuck either buying all new file trays or dealing with wire trays that don’t stack well anymore. This model solves that problem, you can now 3D print replacement feet (feets?!) and continue using your file trays when the original rubber feet wear out. You can also now color coordinate your file trays too if you like!

I created this at the request of a family member who’s a teacher and has a lot of papers to keep track of. Hopefully it can help some other people out there or at least give someone another excuse to play with the 3D printer some more 😉

This model is confirmed to fit with these trays:

Side load tray p/n 62112: https://amzn.to/3Zyp3h8 (affiliate link)

There may be more part numbers it fits, these are the ones it's been tested on.

Filament:

Print in TPU. The TPU in the 95A hardness range works well. I've had good luck with YOYI brand TPU, here is the direct link if you want to try it https://amzn.to/469wWMz (affiliate link)

Printing:

I used .4 nozzle, 3 walls, 30% grid infill, no top layers, no bottom layers. 

I found that the top and bottom layers make the part stiffer and harder to snap onto the wire tray. If you do print with top and bottom layers consider reducing the walls and infill.

Notes:

This was not designed to work with PLA. I could see a modified design possibly working with ABS or PETG with some adjustment and testing of the clip on area. I've included a .step file so it should be easy to remix if you feel like giving it a shot!
