We are now making final plastics decisions and setting up the final run of 1000! Just wanted to share these images as the samples arrived moments ago and they look great.

There are polypropylene samples (PP) and ABS samples. The ABS ones are a bit better shaped, less warped. But ABS is less recyclable. Mathew and I will discuss momentarily.

Update

Screws arrived from Portland, here's what the ABS part looks like screwed together. Rad!

Update 2

"Swirling" issues seems to be delaying the production :-( we'll keep you up to date but should be resolved quickly:

doesn't look like much of a fight-- the ABS wins hands-down in that last photo. The warping of the diffraction grating mount-plate for the PP version is going to create trouble by "doming" out the diffraction grating.

I wish we could go with the more easily recycleable, solvent-resistant plastic (PP), but I don't think we can.

Can't wait to play with them myself!

They will shortly be in the mail to you, Mathew. Thanks!
