Convert a file from m3d to f3d

Design a case model for an electronic device for 3D printing, and also for future use with a syringe press. The case must have openings for USB-A, USB-C, BH-8 connector, display, a hole for an internal reset button, openings for buttons and button pushers. The board can be completely redesigned if your design is more ergonomic. An approximate appearance is shown in the photo.

I wish to create a 3D visualization of the room's interior to understand the comprehensive layout of the furniture and the overall picture after the renovation. I already have all the photos of the furniture elements; they need to be arranged in the space to give the room the appearance it should have after the renovation.

Modification of the STL model of the impeller for 3D printing (PETG)There is a ready STL model of a two-blade propeller for a jet ski SUP board. The geometry of the hub and the seat for the shaft are completely satisfactory, they do not need to be changed.What needs to be done:“Cut off” the old 2 blades from the existing hub.Design 3 new blades from scratch.The radial gap between the edge of the blades and the inner wall of the housing (nozzle) must be strictly 1.5 mm.Technical data for calculating angles and pitch:Motor: Brushless, KV\ 200 (diameter about 50 mm).Power supply: 42 V battery (BMS 60 A).Controller: VESC 75200 V2.The model must be optimized for FDM printing with PETG plastic (strong fillets at the junctions of the blades to the hub).

I need to create a visualization of the bedroom according to my technical assignment. The existing furniture should be replicated, or similar ones can be used, and the area opposite the bed should be completed with an electric fireplace and a television. There should be hidden lighting with moldings on the ceiling. Additionally, replace the curtains and add some decor on the walls. The area of the room is 18 m². There may be a possibility for long-term collaboration.

Good day. The essence of this project is to create product photos for the website. I will provide the approximate style and designs of the houses. I will provide samples of how it should look. Please send samples of your work. And we will collaborate.
