Chainsaw Oil & Gas Cap Tool — Alaskan Mill & Hot Muffler Clearance

This tool provides extra reach and leverage for opening chainsaw oil and gas caps.

I designed it because, when using an Alaskan mill jig with my Echo chainsaw, the oil cap is especially awkward to reach. One careless move can put your hand in contact with the hot muffler. Ouch. This tool makes the cap easier to access, provides good leverage for turning it, and helps keep your fingers farther from the muffler.

It fits both the oil and gas caps on my Echo chainsaw.

PETG should be a suitable material for this print, but avoid leaving the tool resting against hot metal. I printed mine in Prusa PCCF on a Prusa Core One+ using a hardened nozzle. PCCF offers better heat resistance, but PETG should be suitable for normal use, especially since the alternative is reaching in with your fingers.

Print notes:

• A standard PETG print should likely work with supports.

• I printed mine in Prusa PCCF using the 0.20 mm Structural profile.

• I used 5 perimeters for extra durability.

• I used adaptive variable layer height.

• I painted supports under the broad flat areas, leaving gaps around the edges so the supports would not interface with the vertical surfaces.

• The supports released very easily; mine broke free on its own when I removed the print from the build plate.

I included the 3MF file so you can see the support strategy that worked well for me. I also included the Fusion archive in case you use Fusion 360 and want to modify the design.
