Misprint Fruit Crate – Bin for Failed Prints and Prototypes

A crate for prints that didn't turn out perfect

Every maker ends up with a pile of misprints, test pieces and prototypes that are still perfectly usable. This little slatted fruit crate gives them a home and an invitation: take one.

The idea comes from the "imperfect produce" crates at the market: not pretty enough for the shelf, still perfectly good. The sign plays the same joke for non-makers: the fruit is printed in the wrong colours (a purple banana, a blue pear…), a misprint anyone gets at first glance, even with no idea what a 3D printer is.

The included sign reads ZACHRAŇ MĚ – prototypy a nevydařené výtisky (Czech for "Save me – prototypes and failed prints"). A blank version is included too, so you can add your own text in the slicer.

Features

• Crate: 180 × 126.7 × 80 mm (incl. sign rails), wall 3.6 mm

• Corner battens, triangular inner corner posts, floor with board grooves, hand holes in both end walls

• Slat gaps are blind grooves (2 mm deep, 45° ceiling), so there are no long bridges, and small items can't fall out

• Swappable sign slides in from the top into grooves in the front corner posts, with a 45° lead-in and a bottom stop

• Sign: 171.3 × 50 mm, 4.2 mm plate, 6.6 mm with relief; free text area about 102 × 37 mm on the blank version

• Optional wood grain inlay (about 12 % of the wall area, 0.8 mm deep) for a second, brown filament

• No supports anywhere

Files

• misprint_fruit_crate.stl – crate, single material (no grain)

• misprint_fruit_crate_body.stl + misprint_fruit_crate_grain.stl – crate with grain inlay; load both together as one object with two parts

• misprint_fruit_crate_sign.stl – sign with text

• misprint_fruit_crate_sign_blank.stl – sign with border and fruit only, centre left free for your own text

Print settings

• Orientation: as exported (crate standing upright, sign face up)

• Supports: none

• Layer height: 0.2 mm (required for the sign colour bands)

• Nozzle: 0.4 mm

• Walls: 3

• Infill: 10 % gyroid

• Top/bottom layers: 4 / 4

• Brim: not needed

• The only bridge is the 37 mm top edge of each hand hole, which slicers handle well with default bridge settings

Multi-colour sign (colour by layer)

The sign is a single STL. Colours are switched by layer height, three layers (0.6 mm) per colour:

• 0 – 4.2 mm: black plate

• 4.2 mm: white (text and border)

• 4.8 mm: fruit colour 1 (banana and lemon)

• 5.4 mm: fruit colour 2 (pear)

• 6.0 mm: fruit colour 3 (cherries)

In Bambu Studio, add the filament changes on the layer slider at 4.40 / 5.00 / 5.60 / 6.20 (the first layer of each new colour). Use any colours you like, just don't print the banana and lemon yellow, or the joke is gone.

Important: print the sign on its own plate with Print Sequence set to "By layer". If a multi-part object (like the crate with grain) shares the plate, Bambu Studio disables layer-based filament changes.

Without AMS: add a pause or M600 filament change at the same heights and swap the filament by hand.

Blank sign: add a text part on the top face of the plate (at 4.2 mm) with a depth of 0.6 mm, and it lands in the white band automatically. Use a bold font with a lowercase height of 5 mm or more.

Wood grain (optional)

• Print the body in wood-fill PLA and the grain in brown PLA

• On a dual-nozzle printer, put the wood on the main nozzle (it is over 95 % of the volume) and the brown on the second

• The grain sits in about 40 % of the layers, so expect a prime tower and a longer print. If you'd rather keep it simple, print misprint_fruit_crate.stl in wood filament only

• Wood-fill PLA: stick to the profile temperature and don't leave the nozzle idling hot, to avoid clogs

Tips

• Fit test: the sign has 0.25 mm clearance per side in thickness and 0.35 mm in width. Before the long crate print, slice a thin piece of one front corner post with its groove and test it with the edge of the sign

• Print one sign per occasion and swap it in seconds
