Elegoo Neptune 4 build plate wall hanger rack
A wall rack that stores three spare Elegoo Neptune 4 or Neptune 4 Pro flexible PEI plates (235 by 235 mm) on edge so the coating never touches another plate. Each slot is 3 mm wide with a 2 mm rubber-friendly lip, spaced 20 mm apart so plates lift out without scraping, and the plates rest on a 6 mm ledge with a 5 degree back tilt. The rack is 250 mm wide, 60 mm deep and 40 mm tall, printed flat in PETG with two 5 mm keyhole slots on a 200 mm pitch; the same geometry suits Ender 3 V3, Sovol SV06 and Bambu A1 plates by changing the width.
Spare plates piled flat pick up scratches and dust. In SpeakCAD you give the plate size and how many you own, preview the rack in the browser without paying, widen the slots for a textured glass plate in the chat, and download the STL.
