Many tools for these found on trials motorcycles tech forks.

Air Gap Tool.stl > This rule for setting air gap on forks. After printing the rule, you will need an small lenght of bowden tube [De=4mm; Di=2mm] and an syringe.

Internal wrench alum 13.stl; Internal wrench alum 20.stl; Internal wrench steel 13.stl and Internal wrench steel 20.stl > These tools are for holding internal cartridge while unscrewing bottom bolt. Since internals are diffrent for aluminium forks [black or brownish color] and steel forks [chrome or gold color] there are tools for aluminium and steel forks. The ones with 13 number on file namber uses square 1/2" from any socket driver set but can not be used on hydraulic side. I made these tools because not everybody will have access to the needed tube for tools ended with 20. Tolls ended with 20 number use a lenght of square 20mm x 20mm tube [wall 1,5mm] commercially known as "metalon" tube. This is the best option because tool is hollow and can be used on both sides of suspension. You need to print ony one of these four files according to your choice.
