ProStruder Locking Lever

One of the things that I thought was cool about the expensive BondTech extruders was the ability to release the filament such that you don't need to continually press a button when loading or removing filament.

The ProStruder is easily modifiable and gave me a perfect opportunity to add this feature. This button/lever/whatever replaces a pair of acrylic and one M3 washer at the end of the filament release lever. It allows you to release the filament normally or, with a inward push, lock the lever in the down position for easy filament access.

I printed this in PETG to match the other bits as well as for durability. I'm pretty sure that PLA would be good enough if you keep this in a room temperature environment.

When installed, this may be clamped a bit too tightly to move freely. I rubbed a bit of bees wax on the sides near the hole. If you don't have bees wax, candle wax would work fine here.
