About this 3D model

Simple dice or components holder for the Brimhart Board game table (linked below). Looking for any help making remixes for other attachments or other ideas to help improve this as I am very much a beginner when it comes to 3D modelling. The most important thing was getting the slide piece to work properly. V1 - Standard, based off of the drink holders that come with the table. V2 - 10mm deeper pocket to allow for dice to rest more securely in the holder V3 - 10mm shorter so it doesn't stick out as much if you don't want people to bump into it. Also, 5mm deeper pocket than V2. https://www.amazon.com/dp/B0D176NZH9?psc=1&ref=ppx_yo2ov_dt_b_product_details
