Further update - while looking for alternatives I found this new page on GraceBio's website gracebio.com/product/secu...
So it looks like they may have indeed recently started making them but just dont reply to my emails any more 😠😠
Not cheap ($115/25pk) but good to have a source.

Alternatively, a DIY solution might be possible. If anyone has any ideas on a suitable non-toxic double-sided adhesive sheet material, then purchasing those and using either consumer grade die-cutter or online-die cutting services could be a straightforward solution.

Unfortunately we are back to square one. @geobellward.bsky.social and @ivan-volkov.bsky.social had found iSpacers (www.sunjinlab.com/ispacer-sele...) looked promising, and custom sizes available so that seems like the next port of call

We have to assume at this point they will not make them and need to find alternative. Only last thing to check is if many others email techsupport@gracebio.com to ask about GeneFrame replacements it might motivate them? Could also be a US/non-US thing? Not great but worth trying.

Further update on GeneFrames replacements from GraceBio. Recap: their prototypes worked great, and in July they said they were moving to production. I emailed GraceBio beginning of October requesting update about production. Since then I have emailed them 4 times, and have not received any reply. 🔬🦠
