Sheridan PGP Pump Handle w/ Insert

thingiverse

This is the second version of my PGP pump handle, designed specifically for Initeq #10-32 long brass inserts. Previous prints with less than 100% infill cracked when bending the pump arm into place for the quick strip bolt on the PGP2. To avoid this issue, I set the bottom layers to 9999 in Cura during printing. When installing the brass insert, thread it onto the pump arm first and then index it to the marker before melting it into place using a soldering iron. The pump arm should be threaded all the way in when assembled for optimal performance. Tolerances are extremely tight in this design, so if it's too tight on your marker, simply lightly sand the insides until you achieve the desired friction.
