It's the most fun I have had doing a build in a long time. Of the thousands of prints I've made in my 10 years of 3D printing, it might be my favorite. I like the function and the form.\n\nComments: I have run a couple of hundred bolts through it. It took a bit of getting used to, but I think I spent maybe half an hour getting used to the process and sorting them. 6mm bolts tend to not fall and roll all the way to the end and drop off. No big deal, I pick them up and put them in the bin. A bit of 3-in-one oil on the slider pin made it much smoother. I found that less parts in the bin are better as it picks them up too well and they stack up and I tend to get jams. I printed the handle in TPU and did the fuzzy skin as you did. Since the numbers on the tray weren't separate, I used a silver Sharpie to color them.\n\nSuggestions: I had to put a fair amount of force on the handle when using it and it shook apart several times and I had to snap it all back together. A screwed together option would be nice. Specifically, the rotator lid. I don't want to glue it as I need to take it out occasionally to get bolts out that fall down or I get a jam I have to fix. Also, a couple of screws/bolts to hold the base to the main plate would have helped a bit.\n\nI printed the black parts on my Qidi Plus 4, the Blue/White parts on my XL, and the purple/blue parts on the MK4.","rating":null,"likesCount":2,"liked":null,"membershipAgeMonths":0,"modelData":{"model":{"id":"1246643","ratingAvg":"4.6000000000","ratingCount":20,"__typename":"PrintType"},"__typename":"ModelDataType"},"membershipTier":null,"__typename":"PrintCommentType","model":{"eligibleForNomination":true,"id":"1246643","slug":"mechanical-m3-boltscrew-sorting-device","name":"Mechanical M3 Bolt/Screw Sorting Device","authorship":"author","club":false,"excludeCommercialUsage":false,"price":null,"eduProject":null,"ratingAvg":"4.6000000000","myRating":null,"ratingCount":20,"description":"
