For my Pershing 1A 3D build, it's interesting that the TLP paper cone (111 grams) and 3D printed nose cone (113 grams) are virtually identical in weight so far. Keep in mind I did modify the TPL cone to separate at the body like the Estes cone instead of the top balsa cone as the TLP instructions would have you do, so there is the added weight of the coupler. Neither has additonal nose weight added yet.
