I am about to machine up the extra parts I need. It's not much trouble for me to make some extras. If I had some extra bags of parts that comprised of the Lens Mount, the LD Clamp and the Grating support, would anyone want them? I'll charge shipping plus material cost ($10 or so). I can't do extra base plates because the material is too expensive. JLC is cheaper.
Here are the extra parts I made for the performance edition. If anyone wants a set I’ll send them to you for no charge. They are anodised aluminum + Delrin for the laser diode clamp.
