Replace part for Pilot Dr. Grip Ballponit pen

I made this for people that need replacement part for their Pilot Dr. Grip Ballpoint pens. It should work with most of the models as long as they take BRFN-30 or BRFN-10 refills. 

I try to make it exactly the same as the original model, so it will be easier for you to remix it into parts that will be compatible with other refills. 

I print it with 0.2mm nozzle and 0.06mm layer height. If you slow down the print you will not need any support when print it vertically.
