Qidi Plus 4 Nozzle Camera using Creality Nebula

Mounting system for using Creality Nebula camera module as a nozzle camera on Qidi Plus4 printers. Two printed parts are in this project. Plate in orientation as shown in picts here. Print with stiff/strong material,  4 perimeters, 4 top layers, 4 bottom layers, 15% gyroid fill. Use organic supports for overhangs ONLY as shown in pict.

1.  Hotend fan mount with hardpoints - Replaces existing hotend cooling fan mount with one that includes hard points onto which other hardware can attach. This should be printed in stiffest material. Mine are in PETG-CF.

2. Nebula Camera Mount - Raw Nebula camera module inserts into this piece. The camera mount then bolts onto M3 hardpoints of above, hotend fan mount.

Insert M3 Square nuts into pockets of fan mount to create hard points. Always secure secure nuts with M3 x 4 mm screws when hardpoints are not being used.

Replace M3 6 mm self tapping screw below filament cutter with M3 10 mm self tapping screw to secure stabilizer arm of hotend fan mount.
