In the 70s I remember being at Service Merchandise and they had all the Maxi-Brutes, but I had only enough money to buy one. At the time it felt like the hardest decision of my life. I finally settled on the Honest John, but I always wanted the Pershing 1A too. I do have a TLP Pershing on the workbench, but it’s just not the same. Then back at the end of March I decided to get a small 3D printer to give it a try, rocketry parts was one of the reasons. After a few weeks, I realized how useful 3D printing was and decided to buy a bigger better 3D printer, which opened up all kinds of possibilities. Then early last week I stumbled onto this thread by Leo Nutz on TRF https:\/\/www.rocketryforum.com\/threa…a-clone.150742\/<\/a>.<\/p>\n\n\n\n

Holy smokes!<\/p>\n\n\n\n

Leo has done a really good job putting together the 3D files and making them available for the rest of us to use.<\/p>\n\n\n\n

This is my first large 3D project I’ve attempted, plus I decided to use PETG since it can be way tougher and tolerate heat (aka Sun) than PLA. But PETG can be a challenge, especially with stringing. I had several fails at first printing the nose cone, but finally it came together. Leo recommended spiral\/vase mode, which is single wall, but I couldn’t get 0.8mm wall thickness Leo’s parts are designed for, it was always too thin. Switching from a 0.4mm to 0.8mm nozzle would likely solve it, but I don’t have one. So I printed mine double wall in Standard mode, combined with slower printing speed for PETG, my print time was a little over 30 hours combined for the 3 nose cone sections! So yeah, like Leo I can’t offer to print these for anyone either, sorry. The results turned out great!<\/p>\n\n\n\n
