Works well. I thought that the 400 percent wasn't working. Then my kid sat on it, and showed me that I didn't press down with enough force.

Neat trick to build without walls. We set infill to 70 percent to get our desired actor visibility to audience blocking ratio.

Neat "trick" to print a layer without walls. I went another route for my next set of builds, but might revisit this sometime. Advantages: Quick to print, and it does work. As thin as can be! Disadvantages: Being a single layer, offers no structure. Thinness of structure may interfere with some builds. To incorporate into a print, requires assembling parts with different wall numbers and infills. I found 82% infill to be the best mixture of wearer transparency and viewer opaqueness from a distance. Your mileage may vary.

Works. Kids like it, but have difficulty holding the correct tempo. Certainly not a design problem!

Fits well! I can't tell the difference in the rate my dessicant packs wear out to maintain low humidity. Great job.

Suggestions for improvement: 1) Split the models into three. Someone shouldn't need to perform a "cut" in order to print just one, change sizes to selected leprechauns, etc. 2) Yes, this obviously needs supports. But if you divide them into three, I bet you can orient to reduce the supports needed. I'll probably put up an alternate edit soon to address these.

Works well. Advice for "molding" mask also works well.
