Summary

This is a simple print that allows you to buy cheap Sawzall blades and cut with them by hand. It's remarkably fast at cutting if you choose the right blade - I recommend finer-tooth blades like the one pictured. Two machine screws and nuts are required, and a 2nd hole must be drilled into the blade for a 2nd handle anchor point. The handle works best with 9" blades in a recessed, full-tang format. Extra long or shorter blades can be a little harder to work with. The nuts and bolt heads are recessed into the handle for extra comfort. There are many different screw and nut combinations that can work with this handle, but I used hex nuts that are 5/16" from flat side to flat side, and a pan-head screw with a 7mm OD head and 3/8" long. Thread type doesn't matter as long as your nuts and bolts match up, obviously. This was a fairly quick build and can certainly be improved, so feel free to do so. I wanted a minimalistic saw in my tool belt for the times I need to trim up a poor circular saw cut or something. I've not used it for that yet, but have cut many limbs down on a couple of pear trees that needed pruned up. Supports in the hex nut cavity make printing easier and more likely to be successful, but most printers can probably bridge that span without supports. Alternatively, you could print it with the flat narrow side down, or you can also experiment with pausing the print at the appropriate height and placing the correct sized nut into the hole and printing over it in place. I tried this but failed to modify my gcode correctly the first time and haven't attempted again.

Thanks for sharing. Saves me from designing and publishing myself! Printing now.
Cheers!

Well, apparently the Diablo blade I have is different than the one pictured here. Same length (9") but the blade I have is for metal cutting only and is a bit wider than the blade you used. I will design a handle to fit this style blade and post up a revision asap/ Pics etc later!

edit: maybe I will pick up one of these style blade so my Handi-Saw print does not go wasted. I might actually have a couple wood cutting blades a tad shorter in length that should fit.

be warned. one of these pieces is upside down. rough side out. make sure to rotate if you want smooth side out. otherwise, EXCELLENT.

The "Handi-Saw" branded side is up to reduce the chance of a print failure when not using support material in the screw holes - the best orientation for printing without supports however is probably on the narrow side opposite the finger groves. Thanks for taking the time to report feedback, and I'm glad it worked out for you!

This worked out very nicely. I trimmed and drilled it for nuts and a saw blade I had lying around, and I recommend this to anyone thinking about it.

This is awesome!!!

Great idea!!!! This is one of the reasons for having a 3D printer and why I love to look at all the new things people design and make. So simple but oh, so elegant! I will be making a few of these, for sure. Thank you for sharing.

You know, it takes more effort than I'd like to publish designs like this, so I really appreciate your feedback.
