Please excuse my English as German is not a language I write well in. After downloading the stl files, I noticed that some of the parts could use a bit of improvement for fit of bolts, nuts and depth for putting together. In another post I mentioned this but it is on the bottom of someone lese's comment and most folks might not see it. The link for the items is here: https://www.thingiverse.com/thing:4102435 , I gave accreditation for being a remix of the original. Hopefully folks will find it useful. I changed the main gears to a Helical drive engagement as that will allow better transfer of power for the unit (also smoother). I made the nut holding section to fit a hexagonal nut instead of just being round holes. I went through and spaced all the holes for tolerance of the bolts to be used and the normal expansion tolerance of PETG, though it can be used with PLA as well. I added a groove in the lower arm so that if the steel pin extends a small amount (>2mm) it can still function with out issue. I also created a recessed pocket on all the bolt holes so that the head should sit flush on a standard 3mm machine screw. The smaller gear can be press fit but also has a side hole to allow a brass insert for a set screw. I will try to add pictures to this post later once everything is fully up and running (currently build the background for it and a few other minor build issues (like getting drives that will work with it). Out side of that Working on a a base for the Pi and Hat that will allow cooling and possibly allow adjustment of the camera height and a few other ideas that I am working on. Thanks for a wonderful tool.

Have built the board for the raspberry pi and it checks out with multi meter. Raspberry pi powers up from it without an issue. The Issue is that I can't get my router to see it on wifi. If I can fin a 90° connector for RJ45, I am tempted to just use direct wired connection as long as that won't cause an issue with the scanner. Please advise on options to resolve this issue.
