Shelving Bracket/Shelf Rail for 25mm Diameter Spool Holder 2 Sizes

thingiverse

I'm excited to share my first contribution with this community. I've designed a simple, easy-to-print spool holder that attaches to a shelf rail. Since the filament available in my country has very small inner diameter holes, I created this design. It took me about 1 hour and 30 minutes to print the base and arm parts, which are 75mm and 40mm long, respectively. To print these parts efficiently, I recommend printing them on their side for stability. Alternatively, you can print the base vertically or horizontally on the bed for added strength. However, I learned a valuable lesson when I had a knot in my spool - printing it flat can cause breakage. I used PLA to print these parts, but I suggest using ABS or PETG for better durability and flexibility. The first picture shows the measurements of the base part, which requires three M3 screws, two washers, and two nuts. Make sure not to overtighten the middle screw, as this can cause the back arms to break. I apologize in advance for any grammatical errors - English is not my native language. I hope you find this design useful! Update: On April 23rd, I made some adjustments to the base part, allowing users to secure it with an M3 nut and a central screw. This ensures that the base remains stable and doesn't move. Update: On April 25th, I added two new arm variants - one is 40mm long, while the other is 95mm long.
