Good way to print out and have kids build simple circuits.

Nice build…but…I can’t imagine trying to breath thru leather. May need to put a few holes in it and add in a cloth filter.

You use this with some transparency sheets (old school sheets where you printed out your “slides” for displaying on large screens).

Another nice build. Also built from scrap. It is roughly 3/4 inch plywood being used (author had a 1/4 and 1/2 inch that he combined).

This one I could do. I have to say I was impressed with the build (the author “bends” the plywood to a curve). One thing the author could have done a little differently is to put grooves into the back of the shield to help with bending it, since it will all be filled in with woodglue in the end.

Simple and the author includes a pattern you can print out. Made one of these myself, but added a few extra layers.

Since I am a glasses wearer, I am interested in these sort of protection systems over straight masks. Downside is you need a good size table to print it out.

Nice build. If you have a printer that can handle the size. The “gate” thought is not printed but a piece of plexi glass. Not sure if I would build on of these myself. If my printer could handle it.

Nice build for a rocket launcher. I was impressed with the 1 way valve build for this too.

But I don’t know if I would have the patience to make this. The author traces all the patterns on the shield first, then using a dremel in router mode, cuts out the outline, then chisels out chunks, then burns in around the patterns, then sands and stains…yeah…me, I think I would upgrade my CNC first.
