Turn Reusable Shopping Bag Into Bicycle Pannier [3D Prints]

Who is this for?

Are you a reusable shopping bag user yourself and started cycling recently? Do you carry your grocery bags on your bicycle handlebars and looking for a better way to carry your loads? Or are you considering switching to bicycle panniers but doesn't want to break your bank for one and still want to keep your folding bike foldable? 

Omni Pannier Clips

This is a Passion Project of mine that I developed to combine my habit of having a reusable shopping bag; which I carry around with me and doing my household grocery shopping on my bicycle around my neighborhood. Ever since I got one back in 2007, I always have this idea in my mind that a reusable shopping bag could be more versatile. Combined with me owning a folding bike, this lifestyle got a lot more interesting during the pandemic periods

Equipment and Tools:

A 3D Printer - For printing the Clips, if you don't have a 3D Printer, you can send your files to a 3D printing shop.

Cura/Any other Slicer Software - for 3D Printing, any other slicing software will do.

Things you can get at your local Hardware Stores / Supermarkets.

1 x Pliers - To use to tighten the nuts and bolts.

3 x M6 Screws and Nuts(16mm or 20mm) - Cheap and easily purchase from any hardware stores.

Any Fabric Reusable Shopping Bags - With a little imagination, the clips can secure on most fabric bags.

Get any reusable shopping that you like to use, I recommend bag made of fabric, thicker material as these will be strong enough for pannier load carrying.

For those that are interested. I'm have upload my 3D Print files for the clips onto Cult3d web store, feel free to purchase them over at there.

The Print Files:

3D Printed Parts:

• 3x Omni Pannier Clip MK-II Hook.stl
• 3x MK-II Cover Type A.stl

Filament Type:

• Print with PLA or PLA+

My 3D Printer Settings in Cura:

• Layer Height: 0.3mm
• Wall Thickness: 1.2
• Wall Line Count: 3
• Infill Density: 20 or above
• Infill Pattern: 3D infill type; Octet
• Printing Temperature: 185c
• Build Plate Temperature: 45c[Or 0c if no heat bed]
• Print Speed: 60mm
• Support Placement: Depends on you
• Support Overhang Angle: 50
• Build Plate Adhesion Type: Skirt

I recommend printing one parts at a time for best print quality or you can just send the file to a 3d printing shop to get your printing done. I used PLA/PLA+ as they can be easily disposal; burned or compose and they are common option you will find in 3d printing.

For optimizing the prints, I would print with at 50% infill, supports only for parts connected to the print bed with only the screw holes tiny overhangs without supports.

Step 1 - Place the hook piece against the top lining area of your bag, take your time to find a good spot. I recommend aligning it next to the handles of your shopping bag for good balances.

Step 2 & 3 - Hold the hook piece in place and clamp the back cover piece on. Apply pressure and hold it in place.

Step 4 & 5 - Screw the M6 Screw and Nut together.

Step 6 - Secure the Nuts and Screw tightly, I recommend using a piler for this.

Once the Clips are on, feel free to attach them to your bicycle rack and start carrying your groceries or cargo!

With this clips, you can do your Plastic Bag Free Grocery Shopping more easily. With a little imagination, the clips can secure on most fabric bags. I used mine clips on a couple of bags, from carrying larger cargo to simply attachment my daily messenger bag to my Bicycle Rack or Wheel Chair.

I really enjoyed working on this passion project over the many months of developments. I learned to design functional 3d prints and how to print them in correct direction for stronger prints.

I really hope these clips will help people reduce their plastic bag usage, maybe not double bag so much. Increase the up take on reusable shopping bag or even help people be more environment and sustainable when doing they grocery next time.
