I wanted clamps for a Felder K500. I got the Felder manual ones but they were cumbersome and slow to set and release. I ended up using Kreg KBC6 Automaxx Bench Clamp, 6 Inch with this model to adapt it to the felder T-Slots.
I've had trouble with the base breaking so I ended up printing it with PAHT-CF and 100% infill. That's been good so far.
I use ¼ bolts for the t-slot clamp. The Kreg came with a bolt in the base which I designed around.
The author marked this model as their own original creation.
