Minisaurs are great fun and have a powerful bite with jaws that snap shut!
Well printed Minisaurs have jaws that will snap closed when you hold the tail and flick the legs and are great little helpers around home and / or in the workshop or office as a peg / clip / clamp. They have a huge bite relative to their size!
At standard scale Minisaurs will print at 75mm long... so are really small. This makes them just the right size to use as a fun key fob that can even be clipped onto things to hold your keys up. Well set up / precise machines will print Minisaurs well at this size and hey should be free to bite and snap their jaws straight off the build plate. If not, uniformly scale the Minisaur's file up a small amount (which will increase clearances) and the jaws will be free to move. If in doubt scale up uniformly by 5 - 10%... it will still be a small print.
Scale them up!
The posted file is the smallest size recommended for printing.... and they scale up great. 125...150...200% all work really well and the bigger you print them the stronger the bite and louder they snap their jaws. Make sure you always scale uniformly.
Minisaurs are a fully enclosed print that has an internal spring section. To make the spring action 'snap' use higher than usual shells and infill. At standard scale 3 shells / 35% or more infill is recommended. As you increase the size infill can be reduced.
Great fun to fidget with yourself... make the jaws snap... useful as a clip / clamp / peg... and also a novel gift.
Print in your favourite colors... and print lots. The Minisaur age has begun!
