Yes, Ks cancels the previous pledge because it is no longer available and replaces it with an available one. We therefore advise you to make these changes only after the campaign, during the pledge manager phase.
At the end of the Kickstarter campaign, all backers will be invited to a new web platform. The "pledge manager" phase will then begin and it will be possible to modify your order, buy add-ons or other products and pay the shipping costs. In this phase, you can also choose the color you prefer.
An ".stl" is a file that can be immediately uploaded to any 3D printer to bring its content to life. The honeycomb structure of AdapTableTop allows you to fit different accessories as if they were "Lego", therefore it will be possible to use any addon according to your needs.
All addons, as well as pledge changes, upgrades and shipping costs, will be managed in Pledge manager, after the Kickstarter campaign. For more information on the Pledge Manager phase, consult the FAQ.
