CAD Designer for Unique No-Drill Bracket

Custom Adjustable Mounting Bracket (CAD Design) – Open Slot, No Drilling, Wall-Mounted Memorial Accessories

I am looking for a mechanical / product designer (CAD) to design a simple but precise stainless steel mounting bracket for memorial accessories (vases, candle holders, LED frames) used on columbarium urn stones.

This is not decorative design, but a functional, respectful, and safe mechanical solution.

Core Problem

Most columbarium niches have existing mounting bolts with nuts (usually one at the top and one at the bottom).
These bolts must NOT be removed, for safety, respect, and risk of stone breakage.

I want to attach accessories without drilling, without glue, and without removing any nuts.
Project Description

I am looking for an experienced mechanical / CAD designer to design a small adjustable mounting bracket for wall-mounted products such as:

Memorial vases

Candle holders / lanterns

Small decorative holders

This is not a decorative render project — I need a functional, manufacturable design.

Key Functional Requirements (VERY IMPORTANT)
1. Open Slot System (Critical)

The mounting plate must have a fully open vertical slot

The slot must be open at the bottom, not a closed hole or keyhole

The product must slide over an existing wall nut/bolt

No loosening or removing of the wall nut is allowed

This avoids:

Stone damage

Risk of cracking memorial stones

Exposure of what is behind the stone

The product slides down over the nut → nut is tightened → product is locked.

2. Adjustable Height

The open slot allows vertical adjustment (a few centimeters up/down)

Used to fine-tune height alignment of the vase / candle holder

3. Distance From the Wall

The bracket must hold the product a few centimeters away from the wall

This is important because:

Stone can crack from heat

Candles or lanterns may get warm

A straight spacer or angled offset is acceptable
(no curved shapes required)

4. Bracket Design

Simple bent metal part (L-shape / Z-shape / folded plate)

Thin but strong (e.g. stainless steel or coated steel)

Designed for powder coating (black / dark finish)

Compact and discreet — the bracket should be as small as possible

Not visually dominant

5. No Drilling

The design must work with existing wall bolts

Absolutely no additional drilling in stone or wall

Deliverables

CAD files (STEP / DXF / DWG preferred)

Optional: simple technical drawings with dimensions

Design must be manufacturing-ready

Nice to Have

Suggestions for material thickness

Suggestions for load safety

Simple exploded view

Important Notes

I have reference images and rough sketches available

I am open to small design improvements, but the open-bottom slot concept is mandatory

Experience with mechanical brackets, mounting systems, or architectural hardware is a big plus

Who I’m Looking For

Mechanical / CAD designer

Industrial product designer

Someone who understands real-world mounting constraints, not just visuals
