I was getting frustrated with my toneCarrier slipping off-center on the Ulanzi VL49 light I was using to scan film, and ended up using books to hold it in place above the light. But that wasn't very fun, so I designed a simple model that attaches to the cold shoe of the light and holder the toneCarrier's feet securely centered above the light so that the film holder doesn't shift side to side when feeding in film. I hope this is useful for someone else!

The plastic end to the brush on my Roomba broke, but I really didn't want to have to buy new brushes when the tread was perfectly fine. I put together a simple model of the piece to hold the brush in place and have been able to keep using my broken brush. Sharing this to help anyone else who has this problem with their Roomba!
