John brought over the revised version for testing today - it looks great!

He is going to do a little minor editing on the model and then we will get the test SLS print from Xometry and make sure it works OK before placing a quantity order. Be patient - we do need to test the SLS printed version to make sure there are no issues.

Today we used an open end ribbon for the test. However, John made a little modification to the design so that we can install a continuous loop - no need to splice/fuse the ends after installation.

Stay tuned - we still need to identify a ribbon source. I investigated a couple of cheap and available cartridges for other machines, but they have a half-twist in their loops which seems like a good idea because then you print on both sides (Mobius strip). But there is no room in the UGC-136 cartridge to put that half-twist - how odd that they didn't do that.

I made an offer to buy all 30 that the German eBay guy has left - but he still wanted too much. So they are still available if you just can't wait.
