At a glance
- What to print: one insert, split into 4 dovetailed pieces —
file
screen_filling_4_pieces.3mf. - Material: light-coloured PLA (the insert is hidden, so colour barely matters).
- Time: ~6–7 hours total for all 4 parts.
- Supports: none — the parts lie flat on the bed.
- Bed size: the 4-piece version fits any standard printer (Prusa MK-series, Bambu, Ender, etc.). No large-format printer needed.
- That's the whole job. Borja handles everything else: the screen, electronics, framing and final assembly.

Note — the files are
.3mf
(not .stl). Every modern slicer (PrusaSlicer, Bambu Studio, Cura, OrcaSlicer)
opens 3MF directly — just drag it in.Which file do I print?
| File | What it is | Print it? |
|---|---|---|
screen_filling_4_pieces.3mf recommended |
The insert cut into 4 parts that lock together with dovetail joints. Designed to fit a normal-sized print bed. | Yes. This is the one. |
screen_filling_full_stl.3mf |
The same insert as a single ~30×40 cm piece. No joints to align. | Only if your printer has a 300×400 mm+ bed (large-format). Most don't. |
screen.f3d source |
The parametric Fusion 360 model. Lets you tweak inner dimensions, the mat opening, thicknesses/tolerances, or adapt it to a different frame. | Not for printing. Only if a dimension needs changing. |
Print settings
These are the designer's settings (Prusa MK4s). Nothing exotic — any well-tuned FDM printer will do fine.
| Material | PLA, light colour (vanilla / white / grey) |
| Layer height | 0.1 mm, adaptive/variable if your slicer supports it (0.15 mm is fine too) |
| Quality profile | “0.1 fast detail” or equivalent |
| Supports | None needed — parts print flat |
| Infill | Designer didn't specify; ~15–20% is plenty for a hidden bracket |
| Total time | ~6–7 hours for all 4 parts |
Dovetail fit — the joints were a snug fit
at 1:1 scale on the designer's printer. If your printer tends to over-extrude or the parts
are too tight to slide together, apply XY size compensation of about −0.1 mm
(a.k.a. horizontal expansion / hole-and-slot compensation) in your slicer. Don't scale the
whole model — that throws off the frame fit.
