Just a simple block to mount the universal pcb from Precision Piezo to DJDemonD's Piezo20 hotend mount. It has two countersunk holes for mounting the block to the Piezo20 dome part then two holes for the Universal PCB. One version has 3.9mm holes for m3 heatset inserts. The other has 2.5mm holes you can drill and tap for m3 or use small sheet metal screws.
DJDemonD's design works really well but doesn't have a way to mount the universal pcb. As a result, every time I tried to use it, the delicate piezo wires would break after no time. I assembled and reassembled like 10 times before I realized to could bang out a quick adaptor in Fusion360. I'm a little slow but I get there eventually. :D
I printed it in PETG because that's what I had loaded up at the time. In hindsight, clear PETG is not a good filament to use when you want to show off pictures of the item...Anyway, it works.
