An upgrade for Antinafrica's model.(https://www.thingiverse.com/thing:2914233) These are the nescessary parts I designed myself to upgrade the Falcon 9 to the Falcon Heavy. To attach the booster connector, drill Ø 3mm holes. (The official upgrade costs 35 dollars, price on cgtrader). If you're not interested in the Dragon Capsule and just the 'regular' Falcon Heavy, these are the missing parts.
