Astro Pneumatic #101 Mini Grease Gun Filler

This adapter makes it easy to fill an Astro Pneumatic #101 Mini Grease Gun (non-referral Amazon link) from a tube of grease. It was specifically sized for a tube of Motorex Longterm Grease 2000, but should work well with other tubes.

Instead of filling the grease gun by hand and tapping it to remove air, simply place the body over the adapter, press down into the grease tube, and grease will be pushed into the body. Prime, and it's ready to go.

I need to acknowledge the designs from Simon and Karolis, as I was inspired by them, but as their designs didn't fit this grease gun I drew up a new one myself.

Included is the Fusion 3D file in case you wish to modify it. Excuse the poor quality sketch, I was just quickly knocking this up to fill my new grease gun.
