1. The Model in Brief
A stackable drawer system consisting of three part types:
- Housing — closed all around, only open at the front; a rail inside. Stackable via a 45° nesting rim
- Drawer — slides on the rail, decorative front with recessed handle and relief
- Insert — removable compartment trays that fit into the drawer
Each "level" consists of one housing + one drawer; the levels are stacked
Print Orientation (all without supports)
| Part | Position on bed | Why support-free |
|---|---|---|
| Housing | on its back, front opening facing up | Rail runs vertically, nesting rim is 45° |
| Drawer | flat, opening facing up (bottom of tray on the plate) | Open box, front stands vertically — no cantilever |
| Insert | flat, opening facing up | Open tray, no overhangs |
The export modes (part) already orient the parts for printing
2. Quick Start — Good Print Settings
For most users, the default values are sufficient. If you only want to change a few things:
- Size: Adjust unit_width / unit_depth to your space (Default 120 × 150 mm)
- Quantity & Heights: Set drawer_count and h1…h6 (mix shallow + deep drawers)
- Appearance: Choose relief_style (Diamonds / Vertical ribs / …)
- Print: Export part = Housing / Drawer / Insert with sel = Drawer 1…N, or part = All parts flat → in Bambu Studio "Split to Objects"
- Test fit: Print one drawer + its housing once and check the sliding fit before printing the entire tower
Recommended Slicer Settings
| Part | Layer height | Walls | Infill | Supports |
|---|---|---|---|---|
| Housing | 0.2 mm | 3–4 | 15–20 % | none |
| Drawer | 0.2 mm | 3 | 15 % | none |
| Insert | 0.2 mm | 2–3 | 10–15 % | none |
Material: PLA or PETG. Two-color without AMS = simply print housings and drawers separately in different colors
3. All Parameters in Detail
[What to build] — What is built/exported
| Parameter | Values | Meaning / Tip |
|---|---|---|
| part | Assembly / Housing / Drawer / Insert / Print plate / All parts flat | Assembly = only preview of the entire tower. For printing, select a single part or All parts flat (all parts separated on one plate → "Split to Objects") |
| sel | Drawer 1…6 | Which drawer size is printed during single export (1 = top) |
| preview_open | 0–160 mm | Preview only: how far the drawers are shown pulled out |
| preview_inserts | On/Off | Preview only: display inserts too |
| render_only | All / Housings / Drawers / Inserts | For renders only: exports only one material group as STL. For printing, leave as All |
[Overall Size] — External Dimensions
| Parameter | Default | Tip |
|---|---|---|
| unit_width | 120 | Width of each level. Must fit on the build plate (printed standing = height in print = unit_depth) |
| unit_depth | 150 | Depth = extension path. Attention: in print, this is the build height of the housing/drawer → must fit your Z-height |
| corner_r | 4 | Rounding of the vertical outer edges (0 = sharp) |
Build plate size check: Housing/drawer are printed lying on their back. Build height ≈ unit_depth, base area ≈ unit_width × total height of the level. For large unit_depth, check the max print height of your printer
[Drawers] — Quantity & Heights
| Parameter | Default | Tip |
|---|---|---|
| drawer_count | 3 | Number of levels (1–6) |
| uniform_height | Individual | Uniform = all drawers have the same height (drawer_clear_h). Individual = individually via h1…h6 |
| drawer_clear_h | 50 | Usable height for Uniform |
| h1 … h6 | 35/50/70/… | Usable internal height per drawer (top → bottom). Shallow compartments for small parts, deep for larger items |
[Shell / Walls] — Wall Thicknesses
| Parameter | Default | Tip |
|---|---|---|
| shell_wall | 4.0 | Housing sides/back wall. Min. 4 mm, because the groove uses half the wall (→ ≥ 2 mm remain) |
| shell_tb | 2.4 | Housing top/bottom |
| drawer_wall | 2.0 | Drawer wall. Thin is okay by default (rail_mode 0); only increase to ≥ 4 mm for rail_mode 1 |
| drawer_floor | 2.0 | Drawer floor |
| front_t | 3.0 | Thickness of the decorative front plate |
[Slide Rail] — Rail/Rib (the Sliding System)
| Parameter | Default | Tip |
|---|---|---|
| rail_mode | Groove in housing + rib on drawer | Switchable. Alternative: Rib in housing + groove in drawer. Choose what is more stable for your walls (groove removes material) |
| rail_h | 5.0 | Height of the rail |
| rail_wall_frac | 0.5 | Groove/rib depth as a proportion of the wall (0.5 = half wall → wall is not cut through) |
| rail_clear | 0.35 | Sliding clearance per side. Most important fit value: if it binds → +0.05; too loose → −0.05 |
| rail_backstop | 3.0 | How far in front of the back wall the groove ends (insertion stop) |
| floor_gap | 1.2 | Distance of drawer bottom above the housing bottom |
| side_gap | 1.0 | Side clearance drawer ↔ housing wall |
| top_gap | 1.2 | Clearance drawer top edge ↔ housing top |
| pull_stop | On | Small rounded detent (ball) at the front of the rail: the drawer can be pushed in and gently latches against falling out. Off = no stop (then pay attention yourself to prevent falling out) |
| pull_stop_h | 0.4 | Detent interference (mm) — how far the nose protrudes over the rib. Larger = tighter (harder to pull out); too large = drawer can no longer be pushed in. Range 0.2–0.8 |
[Stacking] — Stacking
| Parameter | Default | Tip |
|---|---|---|
| stack_lip | On | Nesting rim: foot at the bottom, pocket at the top → levels self-center when stacking |
| lip_h | 3.0 | Nesting depth |
| lip_wall | 3.0 | How far the rim is recessed from the outer edge |
| lip_clear | 0.3 | Fit of the nesting rim. If stack wobbles → reduce; if it jams → increase |
| stack_gap | 0 | Additional gap between levels. 0 = flush (normal). Only increase for visual separation |
[Front & Handle] — Front & Recessed Handle
| Parameter | Default | Tip |
|---|---|---|
| front_gap | 0.8 | Gap of the front to the housing opening (per side) |
| front_r | 6 | Corner rounding of the front plate |
| handle_w_frac | 0.42 | Width of the recessed handle (proportion of front width) |
| handle_h | 12 | Depth of the recessed handle from the top. 0 = no recess. More = better grip |
| front_inner_chamfer | 5 | 45° inner chamfer on the upper inner edge of the front (cosmetic, less sharp edge) |
[Front Texture] — Relief/Appearance
| Parameter | Default | Tip |
|---|---|---|
| relief_style | Diamonds | None / Diamonds / Vertical ribs / Horizontal ribs / Dots / Crosshatch |
| relief_size | 7 | Grid/spacing of the pattern (mm) |
| relief_depth | 0.9 | How far the pattern protrudes (mm) |
[Inserts] — Inserts (Compartments)
| Parameter | Default | Tip |
|---|---|---|
| ins1 … ins6 | per drawer | 0 Open · 1 = 2 compartments L/R · 2 = 3 compartments L/R · 3 = 2×2 grid · 4 = 2 compartments front/back · 5 = 3 compartments front/back |
| insert_clear | 0.3 | Fit insert ↔ drawer (per side). If it jams → increase |
| insert_wall | 1.6 | Wall thickness of the inserts |
| insert_floor | 1.6 | Floor thickness of the inserts |
| insert_h_ratio | 1.0 | Height as a proportion of the drawer's usable height. The height is automatically capped below the recessed handle anyway |
| insert_open_front | Open front | Omits the front wall of the insert (the drawer front closes it) → saves material and keeps the recessed handle clear |
4. Adjusting Fit Correctly (Troubleshooting)
| Problem | Cause | Solution |
|---|---|---|
| Drawer jams / is stiff | Sliding clearance too small | rail_clear +0.05 (possibly also side_gap/top_gap +0.2) |
| Drawer wobbles / too loose | Sliding clearance too large | rail_clear −0.05 |
| Drawer falls out | No/too small stop | pull_stop On, increase pull_stop_h (0.5–0.7) |
| Drawer cannot be pushed in | Detent nose too large | decrease pull_stop_h (0.3) or pull_stop Off |
| Stack wobbles | Nesting too loose | decrease lip_clear (0.2) |
| Levels do not fit together | Nesting too tight | increase lip_clear (0.4) |
| Insert jams in the drawer | Too little clearance | increase insert_clear (0.4) |
| Recessed handle too tight | Too shallow/narrow | handle_h 14–16, handle_w_frac 0.45 |
| Groove cuts through the wall | Wall too thin | shell_wall (or drawer_wall for rail_mode 1) ≥ 4 mm, rail_wall_frac ≤ 0.5 |
Bambu Tip: If a fit is slightly too tight, the slicer value "X/Y hole compensation" or "Elephant-Foot compensation" often helps instead of changing the model
5. Print Sequence
- Test: Print one housing + one drawer, check sliding fit (rail_clear)
- For each level, print 1 housing + 1 drawer, plus the desired inserts
- Push in the drawer (rib slides into the rail; the rounded detent nose gently clicks in and holds it)
- Insert the trays
- Stack the housings — the 45° foot centers itself in the pocket of the level below
TIP: For inserts that have no division, only the drawer can be printed without its insert
Happy printing! 🧡
