For anyone that's interested in printing one for themselves, I will be uploading the model files for a really simple single shot tray for the Urban to the GrabCAD website this weekend. This is basically a simplified version of the single shot tray sold for the BSA Buccaneer. Very quick and dirty, so there's no magnetic catch and not pretty at all. But tested with maybe 100 pellets on 3 different printed copies (from two different 3d printers) - so it works. I've only tested with diabolo style pellets. You just slide it into the magazine area, lower the swing arm, push a pellet into the hole, and swing the arm up into position for loading. It's two pieces that I've just attached together with a 4-40 socket head screw. Again, functional but not pretty. I'm not a machinist or CAD jockey, but maybe someone else can make it prettier. Here are some pics. Anyway, the inventor part files will be up on GrabCAD tomorrow. I can put stl files there too if anyone wants.

Here's the grabCAD link for the files in both Autodesk Inventor and stl format:

Hope it's useful to others.

Nicely done and thanks for sharing.

Very nice loader! If I can get one printed, I will add a magnet as I did on my (less effective) tray.
-
Thanks man! Totally awesome of you!

Craig - the magnet is actually in the Urban already. On the oem mag, it attracts the metal faceplate. So you just need to stick a piece of steel in the bottom corner of the base piece - maybe just a small black oxide 4-40 nut or drill a shallow hole and press a washer into it or something like that. (unless you want to make it look nice). If you do make improvements, feel free to share it with everyone.

You are correct - yet another senior moment. I inserted a piece of 5/16" drill rod. :-[
Attachment shows one with 1/4" rod and the other with 5/16" rod (recommended).

I don't have a 3d printer, but I do have a bandsaw, scrap wood and a broken Urban mag. Probably the ugliest tray every created, took about 20 minutes and does the job. If and when it totally falls apart, I'll probably send the files to a 3d printing service as this looks much better than mine, but for now it does the job.

Well done, David!
Your's too, Todd!
Both beats loading via needle nose pliers, like I was doing for awhile ::)

Thanks Dinh!
It really makes the Urban feel like a brand new rifle again. I used to hate single shot, had to rip through a mag as fast as I could load it. Finally got it through my thick skull that, like most things, it isn't the quantity of lead you throw downrange, it is the quality of the shot.
And thanks for the design idea David, I'd been trying to figure out a way to do this without spending $50 on the BSA adapter.
