Most of my orders have really been custom orders (like at least 80%), but I do have a shop at Storenvy
I also have an Etsy shop that I will be moving to soon. I will have both 12mm and 16mm pixel switches by the end of the month (full conversion, not like the ones I previously posted) and I plan on launching my Etsy shop with those. I've also had a Shapeways shop
for about 2 years selling some of these parts (only a portion of my parts are available here). Generally speaking, it is cheaper and faster for me to print the parts at home.
That being said, since most of my actual orders have been custom, I have models for pretty much any blade or hilt size (1, 7/8, 3/4, thick, thin, MHS bladeholder, DIY, etc...)
If you are interested in either parts shown here or elsewhere, the best way to order is to email me directly (see profile) with what you are looking for rather than going through one of the shops. I will almost certainly give you a better price and make sure you get what you need and everything will be test fitted to confirm accuracy (for those parts it's possible for me to test fit).
