Quoted from MrBally:I don't know, but in absence of too-many-pins who constantly reminded us that we should donate to the PHoF and keep donating if we could so Tim could ultimately donate to charity as the PHoF is set up to do; these plastics should be donated to him so he won't have to buy replacements for broken ones.
He can fuse parts from two broken plastics to make one useable part.
Or you can cut a piece of petg, lexan, etc. the size of the missing piece, and then merge them together so they'll be usable in a game.
