EPROM Eraser Deep Drawer — Pinsaver Socket Clearance

Replacement base and deeper drawer for XGecu-style UV EPROM erasers, with room for chips in pinsaver sockets.

https://bbum.net/2026/10/eprom-eraser-deep-drawer/

The original drawer in my UV EPROM eraser was too shallow for chips already installed in pinsaver sockets. This replacement base and drawer recover the space wasted by the original raised runners. The drawer now slides directly on a flat base, with a thinner floor and room for the roughly 15 mm-tall chip-and-socket stacks, including a bit of anti-static mat.

It was printed in PLA+, but PETG would provide more heat resistance. I don’t know how well this will hold up to UV exposure, but I don’t use it often enough to worry about it.

The base fits the four screw holes but leaves off the original feet. The usable drawer space is approximately 116 × 43 × 16 mm.

The drawer is fully removable.

Print settings

Print both parts flat, open side up, at 100% scale.

• PLA+ used for the confirmed print.

• 0.4 mm nozzle; 0.20 mm layers.

• 4 perimeters; 6 top and 6 bottom solid layers.

• 20% gyroid infill.

• No supports and no brim in the saved, tested project.

The included PrusaSlicer project is for a Prusa XL with five toolheads.

Assembly

Unplug the eraser before opening it. Unscrew the four screws on the bottom and remove the original base and drawer. Fit the printed base using the original screws, then insert the printed drawer.
