As I spend more money on my Wargame miniatures I've always defaulted to Cardboard Heroes/Standees/Paper Miniatures for my fantasy role playing games.
OneMonk Miniatures has a few hex bases for paper miniatures and I've been using that style for years. I even made some that match my
CC3 Dungeon Tiles. I had made some multi hex bases for larger miniatures but I can not currently find the files. I use plastic and metal miniatures for my Monster Hunter game and I get really upset that I can't find slotta bases that go Flat to Flat instead of Corner to Corner. I end up cutting the bottom of the bases off at the feet and gluing them directly to a non-slotta base. I've yet to find multiple hex bases in plastic.
I have some form
fillable spell cards if your interested. I did not place the info on the cards directly as that would be a violation of SJG (C) but would be a small matter of copy paste what you wanted if you have them in pdf.
If you like modular dungeons I've made
Hex Tiles to make your own random dungeons using Campaign Cartographer software.
HERE is a great link for Hex Spell Templates that you would need to print on printable transparencies. I've always been meaning to make my own specifically for GURPS but I've not gotten around to it yet.
I've looked into getting a custom tape measure made for GURPS but I have not found a place that would do just 1-6 custom order. I've just been using the printable range ruler from SJG
