HD Shelf Filament Bracket - Performax shelf

This is a bracket that fits on the end of your heavy duty shelf or rack system. This was created specifically for the Performax 77"W x 72"H x 24"D 3-Tier Heavy-Duty Metal Shelving Unit. It is POSSIBLE that it will fit other brands but it was specifically created using dimensions from this Performax rack. This was purchased at Menards and is a popular, low cost steel shelving system.

I created this as I could not find anything that would fit my shelfs and wanted to be able to add filament to the end of the rack for easier access. Obviously you are limited to putting filament on one or both ends of your shelf but this allows you to quickly swap out or keep extra colors close by! I used a SCH 40 (Schedule 40) PVC pipe for this design. It has a tight tolerance of about .001 for 3\4" PVC. I have not tried this with dowls but it should fit that as well. The ID of the holes are tight by design. I did this so you would not have to use screws to hold them in place and also allows you some wiggle room if you have a shelf that is slightly wider

I have also added a lip at the end to allow you to turn these into a true shelf as well in case you want to print some as rack's and some as end shelfs. Personally I have added some shelf to the other side and it works great to keep tools on. I have added fillets on all the edges as well to make this a clean and professional look.

The print profile is setup with support but only uses 2.06 grams of filament (just enough to support the hooks). It uses 4 wall loops and a 8% infill density to reduce print time and filament used. Total print time on a P1S is approximately 3hr (variations depending on other settings). My goal was to produce a strong, decent looking print, that could be printed in under 4 hrs. I printed these in both PLA and also have done some in PETG. Both work fine and have more than enough strength to handle 8 full 1K spools.

This is my first design being shared to the community and would happily make some adjustments to this and welcome all positive feedback on this. Let me know your thoughts and looking forward to seeing your prints as well! Feel free to post some pictures of the colors and how you have them on your HD shelves! Happy Printing!
