Spool holder for DaVinci Pro

thingiverse

I basically modified the original design to fit my needs. The redesigned part still fits snugly into the DaVinci Pro and Pr 3in1 Printers when the top lid is fully closed, just like the original design I appreciated. In my case, the hole that feeds the filament through wore out quickly, causing excessive friction. To fix this issue, I enlarged the hole to 4mm, allowing me to use a standard Teflon Bowden tube to guide the filament from the reel to the feeder entrance. Additionally, I experienced problems with rotating the reel due to friction. So, I added three rollers that allow most spools to rest on at least two of them. This redesign solved both issues and eliminated vibrations that were visible in my prints. Here's the redesigned part. The only material used was a standard M8 thread, which I sourced from my scrap box for extra strength. The M8 thread is embedded in the holder, but this might require printing it with a resolution of 0.1 mm. Unfortunately, I printed mine at 0.2 mm and had to re-thread the hole as a result.
