I have designed my base to hold two gunpla instead of one, this way it saves space as i was running out of room to display my gunpla. it comes with a selection of arms, of different sizes and comes with the normal one gunpla stand if you don't want to display 2. it also comes with a arm for a wall mount if you wish to hang the base on a wall via the hole. The preview image is using the medium size top piece. i have printed this on smaller resin printer, its fairly simple to put together, the arms just slot into the base. and for the double the arm is made of two parts. i would advise to glue the parts together. though the top arm that slots into the bottom piece you can get away without gluing this, allowing you to change it in the future if you wanted.
