Sleeve and Collector 3D Models in STL

This collection gathers 3D models for sleeves and collectors of several kinds: card and toploader storage, cup wraps, connector boots, dust fittings and sliding boxes. Each entry is an STL file meant for a 3D printer, so a holder or a box can be scaled to the items you already own. It helps when a ready-made part does not match the size you need. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«Sleeve and Collector 3D Models in STL»

Card sleeves and toploader holders are usually flat, thin-walled parts sized around a standard card, while storage boxes and caddies add a lid or a sliding mechanism. Coffee cup sleeves are printed as a curved band or a wrap with a seam allowance, and connector sleeves are small tubes that sit over a plug or a cable end. Dust collector sleeves and wall flanges form another group: they are larger, often round, and mount to a wall or a hose.

On the author's model page, check the inner dimensions first, because a sleeve that is slightly too small will not slide over the item it is meant for. Look at the number of parts and whether the design needs assembly, glue or screws, and whether the author lists supports. Material and settings matter as well: thin walls and snap fits behave differently in PLA and PETG, and layer orientation decides how a thin band resists bending. Photos of real prints show more than a render.

If a search for sleeves returns too much, try narrower words: toploader holder, card caddy, deck box, cup wrap, cable boot, connector cap, dust boot, wall flange, sliding lid. Related topics such as trading card storage, desk organisers or workshop dust collection often lead to the same kind of part. Adding a size, a connector name or the object the sleeve goes around usually narrows the list faster than any filter.

FAQ

Perguntas frequentes

How do I know a sleeve will fit my item?
Compare the inner dimensions on the model page with the object you want to cover, and keep in mind that printed parts shrink slightly. If the author gives a tolerance or a test fit, use it.
Do these models need supports?
It depends on the shape. Flat holders and open boxes often print without them, while round sleeves and flanges with overhangs may need supports under the top surfaces. The author's page usually states what was used.
Which material works for a sleeve or a box?
Rigid parts such as card holders and boxes are commonly printed in PLA or PETG. Thin bands and parts that flex are often made in PETG or a flexible filament, depending on how much give you want.
Can I change the size of a model?
Yes, most STL files can be scaled in the slicer. Scale evenly so wall thickness stays consistent, and re-check the inner dimensions after scaling, since a small change can decide whether a card or a cable fits.
