3D Render (can a short animation) with a glowing fluid

A case for the printed circuit board needs to be made, optimized for 3D printing (I mean to consider shrinkage, I will be printing with PETG plastic). The case should consist of 2 parts and be screwed together with M3 screws (with a place for a nut on the other side). Photos of the actual board and the step file are attached in the announcement. The only difference between the model and the board is the LEDs; they have a diameter of 5mm and are soldered in such a way that the center of the LED lens is aligned with the center of the button. USB_CAN_SD_F103.step.png - this is the step file, the .png needs to be removed from the name (otherwise it cannot be added to the announcement). I expect an assembly from the attached step file and the case with 2 parts - so that the functionality can be checked without printing.

Good day. There is a task for creating a 3D space. More precisely, its interior part. The task description is in the file.

Welcome! The company Adaptis needs to update graphic materials for A+ content on our website and on Amazon. We already have a fully prepared design for A+ content (cards, banners, infographics), but they depict a different shape of our product. We have changed the product design and now have its new 3D model. The main task is to create realistic renders of the new product shape and carefully "fit" them into the existing banners instead of the old shape. And immediately your cases

I run a custom candle business and am looking for a talented 3D designer / CAD modeler to help create functional and aesthetic custom details for our products. Specifically, I need a custom-fit wick holder (wick centering tool) designed to sit perfectly atop our unique, custom candle jars. The goal is to create a 3D model (STL/STEP format) that is fully optimized for 3D printing (FDM or SLA) so we can manufacture these tools for our production process.

First render — a close-up of the entrance group to the building and the adjacent landscaping. Add people to make the scene more lively and attractive through quality lighting, greenery, flowers, and detailed textures. Second render — a general view of the courtyard with landscaping elements. Show adults and children relaxing in the area. Use bright sunlight to create a positive and optimistic atmosphere. Add beautiful decorative plants. If there are playgrounds or sports areas in the visualizations, use the same models as in the previous visualizations. General wishes: Create bright, rich, and expressive images. Maximize the perception of the renders through quality lighting. Add more decorative details, greenery, and landscaping elements. Make the visualizations as pleasant, lively, and presentable as possible. I will add the scene in private messages.
