Printing the holder from PETG makes a world of difference! This material has a lot more 'give' than PLA and the fragile retention tab really benefits from this. I've even had a few holders fabricated through the Voodoo Manufacturing service and they are even better than what my modest 3D printer can generate - at a very reasonable price (about $6 each holder).
