I’m commissioning a life-size, wearable snake that drapes from my waist, coils up my torso, and settles its head on one shoulder. The body should be built from black faux fur or a soft plush, yet finished so the surface feels textured and scaly rather than smooth. Inside, I’ll need just enough internal support to keep the coils looking crisp while still allowing me to wrap and adjust the snake easily. A touch of weight—beans, pellets, or similar—will help it stay put on my shoulders without constant readjustment. The head is where realism matters most. I’d like glass or high-quality plastic eyes in a vivid red, set into a sculpted face with defined scales and sharp, pointed fangs. The mouth can be slightly open or closed; whichever better shows off the fangs ...

We are developing a series of tactile relief specimens for a museum exhibit designed to allow visually impaired visitors to explore organisms through touch. Each specimen will function like a raised relief medallion or large coin, where the organism is modeled as a raised form emerging from a circular base plate. These pieces will be 3D printed in nylon using SLS and then installed in a museum reader rail system where they will be touched frequently by visitors. Because of this, the models must be durable, tactilely readable, and optimized for 3D printing. We need 5 tactile relief specimens modeled: 1) Brine Fly 2) Brine Shrimp 3) Burrowing Owl 4) Jackrabbit 5) Pickleweed We will start with one specimen as a paid test. Once approved, the same freelancer will be contracted to complete th...

I will provide you with an existing STL model that now needs to become a clean, fully editable CAD file for 3D printing. Only light tweaking is required—think small fillets, slight dimension fixes, or similar “minor adjustments” while keeping the overall design intact. Because the file will go straight into a slicer, accuracy matters. Please rebuild the geometry so it opens error-free and is easy for me to edit later. I’m flexible on the final format; STEP, DWG, or DXF are all acceptable as long as the result is watertight and parametric.

I have a component supplied only as a 3DPDF. First, I need that file properly converted to a clean, watertight STL. Once the geometry is in STL form, I want to open it in SolidWorks and carry out two key changes: add a couple of functional features of my own and merge the whole piece so it mates perfectly with another part I will supply in STL format. Dimensional accuracy at the interface is critical because these two parts will eventually form a single molded assembly. After the digital work is done, I’d like a short prototype run—just enough 3-D-printed samples for a quick fit-check and functional assessment before we move on to tool design for injection molding. Fast turnaround is important; I’m aiming to review the modified files and receive the print samples as soon...

I already have a first-pass STEP file of a small elephant that slips over a bath tap to filter water with a cartridge system and the form being in silicone to create a playful, food-safe sleeve. The concept works, but things still need attention: the overall shape and proportions of elephant to the filter, we have go it down to what we like so these components just need to be arrange in options, the surface we want to see options in different colours, and the fit onto the filter body needs to be secure and flattering as it must be for moulding. I will send you the current STEP as a starting point. Your job is to clean up the geometry, sharpen for contemporary look, use that we like to create the hero form and enhances playfulness and sophistication, and fine-tune the attachment lip so it...

I need a printable 3D model of Devo-style “plastic hair.” Please base the shape and surface cues on ALL three reference pages I linked so that, when viewed in the round, the finished piece captures details from the 2010 Pomp Black version, the Malformed 1981 variant, and the “Now More Than Ever” promo shots. Level of finish should be moderate—clean geometry with clearly defined ridges and panel breaks, but no ultra-fine texturing that would drive up polygon count unnecessarily. I will supply my exact head circumference and a couple of profile photos; size the model so it rests snugly like a helmet when printed in standard PLA. Primary need is an error-free STL, watertight and oriented for FDM printing. Before final delivery I’d like a simple turntabl...

I need a fully functional open-claw setup

I’m commissioning a 4-foot bronze sculpture of a man seated comfortably, as if pausing beneath a tree. The piece should read as modern in overall treatment—clean planes, simplified anatomy, no fussy texturing—yet the figure must wear clothing clearly reminiscent of George Washington’s era: knee-length coat, breeches, and tricorn hat suggested with just enough folds and seams to be recognisable. Although the attire nods to the 18th century, every other choice should feel contemporary: a calm, balanced silhouette, soft geometry, and an understated patina that invites viewers to appreciate form over ornament. The goal is minimalistic elegance rather than strict historical replica. What I need from you: • Concept sketches showing pose, clothing cues, and proport...

I’m ready to move four different handle designs from digital files to durable, production-grade parts. For reliability in daily functional use, I’d like them built in SLS nylon; if that’s not an option on your machine, high-quality ABS is acceptable. Each handle must match the reference image, or be proportional on all sides to the others, so we’ll be working with multiple custom colors rather than simple primaries or neutrals. Consistent tone, smooth surface finish and color-fastness are essential because these pieces will be handled often, not just displayed. Deliverables • 4 unique handle models printed in the agreed material (additional pieces can be negotiated later) • A small production run of each (exact quantities to be confirmed together) &b...

I have already completed the mechanical concept for an intelligent robotic prosthetic, and the electronics / control system are locked in.

The scope...

I need a working prototype of a compact pool-cleaning robot designed, built, and shipped to Pune by 20 March. Its two core tasks are debris collection across the pool floor and reliable wall-climbing so it can scrub and vacuum vertical surfaces as well. The unit must run on a rechargeable battery pack—no cords in the water—and be steered with a simple handheld RF remote (forward, reverse, left, right, start/stop). A smartphone app or timer isn’t necessary; keeping the hardware lean is key because the entire build, plus packing and freight, must stay within an 18 k INR ceiling. I’m open to clever use of 3-D printed housings, sealed brushed or BLDC thrusters, and readily available filters to hit that cost target while ensuring waterproof integrity. Good buoyancy cont...

I have a .blend file with a lid that must be reshaped so it slots perfectly onto a specific object. I will supply reference photos and measurement call-outs; your task is to reinterpret the existing mesh, adjusting its profile and contact surfaces until the printed lid seats cleanly with no wobble.

Deliverables • Updated .blend with non-destructive modifiers applied • STL export ready for test print • Screenshot or short viewport capture confirming fit against the supplied references ...

Summary We are developing a perfusion lid system for a proprietary vertical-membrane co-culture plate used for advanced cell culture. The lid will enable controlled flow (shear) along the membrane and will scale to the full plate with 12 independent recirculating loops (one loop per column). Each column contains 8 wells (total 96 wells). We prefer 12 independent loops so each column can run different flow rates and/or media conditions. We are looking for a contractor who can support development (concept → CAD → prototype strategy → DFM), not just drafting. We want flow constrained into a defined gap near the membrane to generate predictable laminar shear Target design gap: ~0.3–0.5 mm (must be toleranced and verifiable) Typical target per-well flow range: ~30–20...
