Spool storage system

thingiverse

Hi, here's my design for a spool storage system. The reels I've used are from ColorFab filament. A few things to be done once all parts are printed: each drawer needs to be tapped with an M3 tap. It takes a long time and requires care - you can probably use self-tapping screws, but I prefer using M3 taps. The reel needs to be drilled on one side as the holes are offset; a 3.2 mm drill bit is used for this purpose. The base is tapped with an M6 to fit an M6 screw rod. The screw rod is cut to size depending on how many levels you're building - be careful when tightening it, too much force can crack the base. On top, I've used a single spring washer and nylon lock nut. Two ring insert parts fit together to create one part that goes between levels, providing separation. The top insert needs to be printed with support - a ball bearing is inserted into this part. The required ball bearing has an OD of 19 mm and an ID of 6 mm. The top plug has a small hole in it; it can be tapped with an M3 for easy removal when needed. Two sizes of drawers are included, both with a height of 45mm. I hope I've mentioned everything - I hope you like my design!
