Circular Saw Blade Case for 7 1/4" - 184 mm Blades

This is a model for a case designed to hold multiple 7 ¼" in. / 184mm circular saw blades in a compact form factor. The holder is double sided, and has a hole in the middle intended for 5/8" threaded rod to act as a spindle for the blades on both sides. There are two ported sections on the top to allow you to see at a glance how many blades are in the unit / allow you (with gloved hands or a tool) to get blades out one by one.

Setup: I recommend using washers to create space between the blades to keep the edges of the teeth from making contact. There are lots of 3D models out there for 5/8" washers or you could make one very quickly; I would experiment with size and depth to see what works for you; for a diamond blade, you might want to make a blank that's the size of a blade, for a regular circular saw blade a standard fender washer could work.

You can, but I would not suggest using 3D printed 5/8" rod and nuts/wingnuts, as when this stands vertically the spindle is somewhat load bearing. I've also seen 3D printed versions of threaded rod break very easily under minor load in other applications. I would suggest getting those parts from a hardware store. However, if you have a very strong filament and light blades, this could work; YMMV.

Printing: I've printed mine in PLA but PETG or ABS would also potentially be good materials. There is room to optimize the infill - feel free to remix profiles. I did experiments printing it vertically and horizontally found the model looked cleaner printing it flat, but YMMV.

I'm not sure this requires a disclaimer, but please be smart - if you overload this unit, or you feel like the material you printed it in can't hold a stack of heavy blades, just print a second one, try a different filament material, or figure out another solution. Safety first.

Edit: 2024-11-09: I increased the default profile circumference by a few mm to accommodate all types of blades, including aggressive rip blades (original model is more optimized for high-tooth finish / diamond blades); I also added 4 ports to help fish the blades out from the side out versus the original 2 ports. If you still want the “snug” model I've left it up and renamed it accordingly.

Enjoy!
