Design of stools for cylinders under the style of the hall

It is necessary to convert a set of STL models (3D sculpting/prototyping) into production STEP files with 2D drawings: dimensioning and tolerances. The parts are simple; I have attached an example.

We are launching a series of DIY paper 3D animal figures — they are assembled without glue or tape, only precise cuts and connection locks. Each figure is a separate model with its own unfolding. I am attaching a style reference in the image (crane) — approximately the level of detail, stylization, and silhouette needed. Task: Model a 3D shape of an animal (stylized, not photorealistic) Develop an unfolding for printing on paper/cardboard Think through locks for assembly without glue Break the model into parts convenient for cutting Requirements for the performer: Experience in paper-craft / low-poly modeling Understanding of unfoldings for physical paper (not just 3D render) Portfolio with similar works — mandatory Budget: negotiable. In your response, please indicate your estimated cost for one model (3D development + unfolding + locks) — this will help us decide faster. In your response, please indicate immediately: Cost for 1 model Estimated completion time Link to portfolio with similar works Details and additional references will be provided in correspondence with those who respond.

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).
