In general I really like the finishing kit. I agree with most the putty knife is not much help and a better tool to remove the base would be helpful, although a software change to redesign the base so that it has an edge that guides the tool under the base would be very helpful. Currently I have my finish kit braced against the back of the counter and have a beefer putty knife that I then hit with my hand and yes parts fly off and bounce around. I like the tweezers, but I can see were a small tool to snip supports would be helpful.
I like the foam pad and the alcohol bath, but a finer mesh is needed on the basket for those of us making insanely small parts ;). Never thought I could print a hand gernade for a lego character but you can and it looks great!
I used a razor scraper for awhile, but it was way to easy for me to put some really deep gouges in the aluminum plate so I went back to brute force.
Another useful add would be a UV safe storage container for a partially filled tray, while I could see that being built into the finishing kit I’d be concerned that the banging jerking that occurs during part removal would make resin splash out of the stored tray. But since the resin is so viscous this may not be an issue. I think you could easily store two resin trays under the current footprint of the finish kit.
