Came out really nice and works perfectly. I only wish it was just slightly easier to hold. My fingers always want to wrap around and sometimes stop the spring mechanism, but other than that, really fun to play with and you do get used to how to hold it after awhile.

Hey I made a print profile for a back cover if you want to give it a shot! I had the same experience haha. I kept getting my hand in the way on accident

Came out great. I also did a quick and dirty modification in the slicer to close it off on the end.

Had some issues with the posts breaking on the spring part, he quickly made some modifications to it and works much better now!

Ha ha ha, I changed the knife model into a comb model, so that it may be safer for children (my son insisted that I make one for him)

I printed the plate “with guidance”. This is a much improved design over the original one, especially with the comb. The added track and guide tab really allow the hooks to catch securely. When only printing one blade or comb, there is enough room on the plate to print by object and get a convenient multi-color print without the waste.

Amazingly designed! Great work. The mode could use some further development to get the “ergonomics well done”, but so far it’s great.
