This is just a full-sized flat platform, 264 mm x 224 mm, that attaches to the top of the Honeycomb Alpha Yoke or the Honeycomb Bravo Throttle. It turns the unwieldy curved shape of both into a useful platform that you can mouse on, put your keyboard on, eat a sandwich off of, put your beer, charts/graphs, etc.

Unfortunately, it is incompatible with the Honeycomb Charlie Pedals, so don't try it.

When it loads in Cura, obviously flip it over, flat side down and print it with no supports. You're going to need a big build platform because it's the same footprint as the Honeycomb stuff, 264 by 224. There's already a little mousepad on Thingaverse,so if you need it smaller, go look for Papa_Oso's great Honeycomb Bravo/Alpha Mouse Pad Mount.

This thing is big and flat, so it will warp a couple mm once the print cools, unavoidable really. I added those support rails underneath, but it didn't really help with the warp, unfortunately.

Yes, this is a flat board and you can make this with a little wood and time so if you have your table saw out and the spare wood sheet goods laying around, go do that. But if you have your 3D printer out and $3 of filament loaded, print this and you have a finished product in about 9 hours.
