Servo Powerfeed Type 140 Fast Travel Button Repair

thingiverse

Recently acquired a gently used 1994 Supermax YCM-16VS through work for an absolute bargain. The Servo Type 140 powerfeed functions like new, except the fast travel button's "Rubber Hex" cover was almost completely gone. Unknown to me, I ordered a replacement cover and discovered that the entire unit needs to be disassembled to replace the button cover (not a task for the faint of heart). 3D printing came to the rescue! SOLUTION: I had an extra Echo gas trimmer primer bulb lying around and sure enough it was a perfect fit to grab onto the remaining hex and cover the button. Unfortunately, it protrudes a bit more than the OEM cover and needs a button extension to make it easier to activate the fast travel switch. Rubber Bublb: The largest one in the pack found at Home Depot: https://www.homedepot.com/p/ECHO-YOUCAN-Purge-Blub-Kit-90249Y/300435498 I have two designs: R01: a simple straight-out button that worked great. R02: a mushroomed top to give a bigger button to hit under the rubber cover. NOTE: ID is intended to be a 0.250" hole to snugly fit over the plastic button.
