Summary
This started out as an “Artistic” 3D model, but I thought I would try and make it printable and functional as such.

The chain is in two print-in-place pieces, gently break each link free if needed and work them until they move freely. Assemble the two different lengths by clipping them together with the hooks facing out.
Assemble the front of the blade using a piece of 1.75mm filament as a pin between the guide parts. Press 12mm pins in both sides, make sure they are aligned properly and firmly snap them together.
Slip the cover piece onto the blade (it has a subtle top and bottom) and mount the blade into the top case with two 20mm pins.
Position the bottom case and snap on the cover and handle. Affix the handle with another pair of 20mm pins.
The pins can be a bit finicky, you can use M4 hardware instead.
About:
I was playing around with the Fusion 360 renderer and ended up with the image below. I thought I would see if I could make a printable version. Note the teeth are not on the chain in the included STL files, still having some issues getting them to work out right.
