Tyro 99 drone quadcopter arm replacement
Description
I broke one of the arm of my Tyro 99 and the part is back order. Decided to print one. I did a quick hover flight test and it seems to hold. I will try to print it 105% on X and Y and 98% on Z and Anneal it in the oven and see if it removes some of the flex that the PLA has. I suspect this will induce vibrations... V1.4: Widened the screw holes so tolerances don't force you to drill it V1.5: Added two thicker version and one with the holes not drilled to it's 100% full plastic and stronger. I noticed that the arm breaks along the lines of the holes where it didn't fuse properly. If you print and drill the holes it should be stronger. Annealing process: Tested to anneal in the Oven, shrinkage was no were near what I expected. Part only srunk for 1MM on the long side. Will test to wrap in plastic held on an alluminium foil plate to anneal in boiling water then quench in cold water and see the results.
