For anyone that has used a Snapmaker and changed the filament several times knows how stiff the button spring is inside the 3D printing module.Sometimes feeding the filament through the module takes some time and your thumb can't hold that button forever.
I designed this Filament Module Lever to reduce the amount of force required to keep the button pressed in. The parts are easy to assemble and quickly mount to the module.
All 3D printed parts were printed with the Snapmaker.
In addition to the printed parts, you will also need some hardware: 8 socket screws, 8 hex nuts and 1 metal shaft.
Print the following:
1x Left Bracket
1x Right Bracket
2x Bracket Unions
1x Lever Plate
Purchase the following hardware:
8x socket cap screws (M4 x 15mm) -- Shorter screws can be used, I just used M4x15 since thats what I had on hand
8x hex nuts (M4)
1x metal shaft (1/8" diameter X 1" long)
Assembly and Mounting
Connect the Lever to Lever Plate using the metal shaft. Make sure all support material has been removed. You may need to use some nose pliers to grab the shaft and slide/push it though.
Insert and firmly press the 8 hex nuts into hex cavities
Join the Left Bracket and Bracket Unions together using the hex cap screws
First place the Left Bracket with Unions around the print module and then mount the Right Bracket using more 2 hex cap screws.
Mount the Lever Plate with Lever into place using remaining 4 hex cap screws
