Update:
I have successfully gone to and returned from Canada for my little trip, despite the best efforts of a very grueling customs experience. Since my return, I have organized the rest of the shipment. I ran out of packing peanuts, so there is still some minor filling to do, but that is pretty much done. Monday I will begin the process of stamping and sending the CONUS packages and I will begin filling out the customs forms for the INTL packages.
The add-on trinket I had 3D printed arrived, and the parts work. The fit is tight on some due to the nature of the 3D printing process, but they work. If the extra material proves too tight for the cap you are trying to use, you can always scrape the cruciform with a knife to loosen the fit.
They came in a printed shell to hold the 100 free bits from escaping
And the juicy things were within
The winners of the custom caps have been picked. The method I used to choose the winners was, rolling 2d10 die (one for each digit) gave the number of a row on my spreadsheet. The spreadsheet rows were not in any particular order, and the die have been acceptably random in the past. The winners will be kept a surprise until the package is received. You will know if you have won, because in the ziploc with the 3D printed part there will be a medicine bottle with the cap in it.
The current leftovers which I will be selling off are:
3 stab sets
~1800 quiet click switches
~250 linear switches
~350 click switches
These will be sold first come first serve. Some people have already PM'd me asking for them, and I will be replying to them all tonight. If you buy things now, you avoid extra shipping charges because I can just throw them in with your first box.
