About this 3D model
I designed a filament holder to work with spools 2kg and smaller. Design can be used with or without bolts. I do metric mostly for my designs so I hope the bolt holes are correct. was made for use with https://www.lowes.com/pd/Hillman-2-Count-5-16-in-x-1-25-in-Yellow-Zinc-Standard-SAE-Hex-Bolts/999995510 and https://www.lowes.com/pd/Hillman-5-16-in-Zinc-Plated-Standard-SAE-Nylon-Insert-Lock-Nut/3058723 (you need one pack of bolts and 2 nuts. If you want to use the bolts). If you do not wish to use the bolts there are printable fillers provided. This was made to work with tight tolerances so that it would be like a pressure fit. And remember the angry quacking duck is watching you :)
