Drawer-first paint bottle racks. Enter your drawer, pick your bottles, mix sizes row by row, and download a 3MF to print.
Beta. The seam, pad and dovetail joints are printed and fitted on a Bambu X1C in PETG. Other printers and materials are starting points, so print the test bundle first. The Z-lock key and rear lock bar are untested.
💡 Measurement Tip: Presets marked estimated use a guessed cap size. Check yours before you export.
Caution: Minimal headroom (< 2 mm) may make it difficult to grab and lift bottles out of shallow drawers.
Fractions work in inches, for example 23 5/8. Measure inside the drawer box, and use the height from the shelf or drawer floor to the underside of whatever sits above it (a drawer lid, the next shelf). Headroom is the clearance you want left above the tallest part of the rack, so caps and hands clear it. Drawers differ between models and years.
Standing on end prints each rack with its length pointing up, so the build height sets how long a part can be instead of the bed size, and every layer is the exact cross-section. The dovetail, valley and recess print with no overhangs and the joints fit much more cleanly. The part is as tall as it is wide, so it has to fit under the printer's height limit, and a brim helps. Flat prints the rack lying as it sits in the drawer. The 3D preview always shows the installed position.
Parts and blocks. Rows nest flush and print as one body in blocks of the number set above (4 by default). A dovetail joins each block to the next, front to back. Dovetails need walls about 9 mm tall or more, so they are skipped at steep angles. A block has to fit the bed, so tall stacks split into more blocks. Rows longer than the maximum part length split into equal parts of whole slots.
Tune the joints for your own printer. Start from these dovetail clearances per side:
How tight it fits still depends on your printer, filament and slicer settings. How tight they fit depends on your printer, filament and slicer settings. The test prints so far were on a Bambu X1C with the 0.28 mm Extra Draft profile. In PETG, 0.05 mm clearance per side gave a good fit on the seam tab; in PLA, 0.1 mm fit the dovetail. Print the test bundle for your bottle, push them together, check the fit, then change Dovetail clearance per side in Advanced settings before you print a full drawer.
Parts join at seams with a tab and notch. The dovetail joins one block to the next, front to back. The key is optional and slides in before the pads go on.
