Hey you crazy UL hikers! This is a Fusion360 Port of Jan Rezac's air horn support canister for people to download and adjust a customer sized diameter.
If you're unfamiliar with this idea and what its used for, check out this BPL thread here. (Please read safety note at the bottom of this page)

This idea and design of this stand is from Jan Rezac of BPL. His original post can be found here:

2025 Update:
Jan is now on Printables! If your looking for a close fit, I recently exported every canisters diameter between 35mm - 50mm in diameter, in 0.25 mm increments and gave the files to Jan to host on his V1 page of this stand.
To get the a close fit, go to Jan's V1 post of this stand, measure your canisters base diameter, then match it to the closest larger sized file (stand files are named by the diameter of canister they support) and download it for printing.
Jan's V1 and V2 of this design with removable legs can be found here, along with OpenSCAD source file for modify the diameter:
V2: https://www.printables.com/model/639210-air-horn-canister-stand-v2
V1: https://www.printables.com/model/1166429-air-horn-canister-stand-round/files
If you want an exact fit, you can modify the fusion360 file I'm hosting here for custom sizes, do the following:
SAFETY NOTE:
I think it's important to say this is a practice that has inherent risk. Anyone who downloads this file and attempts to use an air horn as a fuel canister does so at their own risk and assumes the responsibility in ensuring they are doing it in a safe and educated manner. PLEASE read the linked threads and their comments to educate yourself on the risk and their nuances involved here.
Printing:
Print in PETG, ASA, PC, or Nylon for better longevity. No supports needed, will weigh about 6.6 grams for the large diameter designed for 95mm pots. (plan to add a smaller diameter to fit in toaks/snowpeak Ti cups)
The author remixed this model.
I ported the model over to Fussion360 so those not familiar with OpenSCAD can change the diameter.
