3D Printed MPA Quick Release Cheekpiece Riser

[David Lepley]

All,

Not sure if this has been done before but this seemed like the way to go once I had the height where I wanted on the cheek piece. With the ball and detent removed for the height adjustment, the wheel acts as a nut, capturing and clamping the assembly together.

Cheek piece off to on to off again within a few seconds.

First pass in some white PLA I had, more appropriate color and a few dimensional updates to come.

Nice job. If it’s not going to get knocked around a bunch, and the infill is set high enough, PLA will work for a lot of stuff. The main weakness is shearing of layers. If you decide you need more strength you can do a “lost PLA” cast in aluminum. Never done it myself, but I know it can be done. What software are you using to CAD?

I drew it in Fusion360. Once I am really happy with the model I will probably get it printed in solid nylon with a MJF printer or SLS in Al/Stainless.

Between Protolabs and JLCPCB type printing services it’s so easy to get really good parts directly printed once you work out the details in PLA/FDM process.
