From one concept image to 51 outdoor-ready parts
How Cru Bear turned an ambitious monument-sign concept into a production-engineered set of large-format ASA sports forms for a regional sign company.
Create the parts that made the concept possible
A regional sign company arrived with a concept image and a dimensional drawing for a monument sculpture. The artwork already existed. What did not exist was any way to physically make the nine oversized sports forms it depended on.
No mold. No tooling. No off-the-shelf product at those sizes. A 64-inch baseball bat, a 16-inch glove cradling a 7-inch ball, a 13-inch basketball, a lacrosse head at a nominal 12 by 22 inches. Objects that read instantly to anyone walking past, at sizes nobody manufactures.
Cru Bear’s job was to turn that direction into a manufacturable system: modeled, engineered, segmented, printed in gray ASA, inspected, and handed to a professional sign fabricator ready to enter their armature, finishing, and installation workflow.
The artwork was never the hard part. Making it buildable was.
A rendering, a drawing, and a set of finished sizes
The client supplied the monument concept together with a scaled drawing of the individual elements. Cru Bear did not originate the overall monument artwork. Everything that follows is the work of translating someone else’s design intent into parts that could actually be produced.
Client-provided materials. The concept rendering and the dimensional drawing that established every finished size in the package.
| Object | Finished size | Final production breakdown |
|---|---|---|
| Baseball bat | 64 × 5 in | 6 shell sections |
| Baseball glove | 16 × 16 in | 4 shells + 13 alignment keys |
| Baseball in glove | 7 in dia. | 2 halves + 1 ring |
| Basketball | 13 in dia. | 4 quarters + 2 rails + 1 ring |
| Football | 15 × 10 × 10 in | 3 shell sections |
| Soccer ball | 11 in dia. | 2 halves + 1 ring |
| Standalone baseball | 9 in dia. | 2 halves + 1 ring |
| Field-hockey ball | 7 in dia. | 2 halves + 1 asymmetric keyed ring |
| Lacrosse head | Nominal 12 × 22 in | 2 reinforced sections + 4 keys |
| Nine forms | 51 printed parts |
Modeling for manufacture, not for a render
Each form was rebuilt at true production scale. A model that only has to look correct in a render is a different object from one that has to survive segmentation, support, and assembly.
The glove is the clearest example. Webbing, lacing, finger stalls, and a pocket that had to visibly hold a separate 7-inch baseball, all of it modeled so it could later be cut apart and put back together without losing a single detail.
The glove split into printable sections and digitally reassembled, and the clearance check placing the production-scale 7-inch ball in the palm. The selected position produced no triangle overlap and about 0.7 mm of minimum sampled clearance.
Every decision was signed off before it was printed
Approvals were not paperwork bolted onto the end. Each package existed so the client could make a real decision, and so no expensive assumption travelled further down the process than it should.

How nine objects became fifty-one parts
The preliminary estimate was 26 to 30 sections. The final production inventory was 51. That gap is the entire story of the project: every added part exists because something needed to register, reinforce, or survive a real print rather than a theoretical one.
Seams were not placed where they were convenient to cut. They were placed where a finisher could sand and fill them, where alignment could be positively keyed, and where the printed surface pattern would not be destroyed by the split.
Segmentation studies. The 64-inch bat across six sections, the basketball’s four quarters with rails and equatorial ring, the reinforced lacrosse head, the Version 6 field-hockey construction, and the three-part football.
A closer look at the hardest pieces
These are not confessions. They are the reason the package shipped correct. Quality control that stops at the first green checkmark is not quality control.
The bat: watertight, and still not printable
The first connector design read as closed and manifold. It passed ordinary topology checks and sliced without a warning. Physical inspection told a different story: the male insertion sleeves on five sections were resolving as separate rings in the toolpath, supported below the surrounding wall instead of continuous with it.
Cru Bear scrapped the originals and rebuilt the bat as Version 2, adding a release standard that checks actual final-toolpath continuity, not just clean geometry.
The glove: four shells, thirteen keys
The concept called for the ball to sit visibly and proudly in the palm. Too deep and the visual moment disappears. Too high and it reads unstable.
A digital placement audit at exact production scale settled the lower-palm position with roughly 0.7 mm of minimum sampled clearance and no triangle overlap. No molded retainer was added, because the final support angle belonged to the fabricator’s internal armature.
The field-hockey ball: a seam that respects the dimples
The client mesh carried more than 3.5 million triangles. A straight equatorial split would have run right through the dimple pattern and left a ragged joint.
Six iterations later, Version 6 rotated the working surface, locally blended only the seam region, and used two shells plus a directional ring with two opposed, unequal keys so it can only assemble one way.
Where a model becomes a schedule
The release package was 31 editable production projects across 36 physical plates, built for high-flow hardened-steel hotends and split into two deliberately balanced queues so both machines finished together.
A glove section prepared for slicing, and the two production queues running in parallel.
These figures are modeled from the sliced package, not measured from the machines. The 263 hr 50 min combined total is modeled printer occupancy across two machines, not elapsed calendar time.
Why gray ASA
The elements were destined for an outdoor installation and for professional finishing. ASA is commonly chosen outdoors for its UV, weather, and heat resistance relative to general-purpose printing plastics, and it sands, fills, primes, and paints inside a normal sign-shop workflow.
Neutral gray was deliberate. It makes surface inspection honest and gives the fabricator a consistent substrate to coat.
Material is only one input to durability. Service life also depends on the armature, adhesives, seam finishing, coatings, drainage, impact exposure, installation, and maintenance, all of which belong to the fabricator. The forms were supplied as production components, not as a finished outdoor system.
Fifty-one parts, ready for a sign shop
The completed forms in gray ASA. Seams are visible in several images by design: these are components at the handoff stage, before the fabricator’s assembly, seam finishing, primer, and paint.
The finished-part photographs are AI-assisted studio edits of the original production photographs, used for presentation. They are not exact evidence of geometry, seam, texture, or dimension.
Where our work stopped
Being precise about this is not modesty. It is how a fabrication partnership stays honest, and how a sign company knows exactly what it is buying.

A concept became a buildable system
The client was very happy with the completed work, and the conversation has already moved on to a follow-on project. That is the real measure of a fabrication partnership: the next job.
Have a sculptural component that does not exist yet? Bring Cru Bear the concept. We will help turn it into a manufacturable system your fabrication team can finish and install.
Produced for a regional sign company. The original concept and source drawing remain the client’s materials. Cru Bear did not design the monument concept, build the armature, paint the components, or install the monument. Client details are withheld by agreement.
