Specifically designed to match the original factory‑made enclosure of the Tuzhu P1; it is not compatible with the original top cover and requires you to cut acrylic sheets yourself to create an observation top cover. This product can only be used as a complete set with this particular height‑increasing frame; other height‑boosting frames available on the market are not compatible.

Structure and Fastening Solution

1. The main frame is assembled by joining four separate side panels, secured with four sets of metal reinforcing clips that lock the joints tightly. Each clip is fastened with four M3 socket‑head screws, for a total of 16 M3 screws required to assemble the entire frame, ensuring a snug and stable fit at all seams.

2. Acrylic self‑made top cover mounting: The frame includes pre‑drilled M2 screw mounting points, requiring 12 M2 screws to securely attach the acrylic top cover to the frame’s edge strips.

Aesthetic Concealment Design

The edges of custom‑cut acrylic sheets often exhibit burrs or irregular dimensions. This height‑increasing frame features widened, concealing steps that fully mask any imperfections from the acrylic cuts, enhancing the overall visual tidiness of the machine and seamlessly integrating with a self‑cut acrylic top cover to form a fully enclosed observation window.

Printing Process Recommendations

We recommend using PETG filament for printing, as its rounded corner design eliminates the need for additional supports. The modular, split‑piece construction allows for batch‑wise, flat‑bed printing, resulting in virtually no visible seam lines after assembly. Additionally, the thickened frame improves the device’s enclosure sealing, while providing better temperature control during the printing process.
