Read this model as text

The four lamp fittings you find on the Dutch hardware store shelf: GU10, GU5.3 (MR16), E14 and E27. For each fitting the model gives three parts: a dummy lamp, a dummy socket and a printable holder cup. The lamp dimensions follow the lamp standards (50 mm spot face, 10 mm and 5.33 mm pin spacing, 14 mm and 27 mm Edison caps). Socket housings are not standardised and vary by brand, so their dimensions are parameters with typical store defaults. Measure the socket you bought and set them to match.

Description

What is this

What you use it for

Designing luminaires around real hardware. Import the lamp mock and socket mock into your own design to test fit openings, pockets and depths before printing. The holder is a ready component: for GU10 and GU5.3 it is a cup with a front flange, a rear plate with fixing holes for the socket and a pass-through for the lamp base and pins. For E14 and E27 it is a cup the socket housing drops into, with a 10.5 mm hole in the base for the standard M10 lamp nipple. Print the holder in a heat resistant material and use LED lamps only.

Design notes

Everything is built on one axis. The GU holder has its flange at z = 0 and the rear plate at the top, so it prints flange down without support. The socket screws onto the back of the rear plate through the fixing holes, the lamp twists into it through the pass-through. The Edison holder has its closed base at z = 0 with the nipple hole, the socket sits inside and the bulb comes out the open end. The assembly view places all three parts as mounted and cutaway slices it open to show how they meet. The mocks are display geometry, not printable replicas: the GU10 twist lock heads and Edison threads are simplified to rings and stubs.

Parameters

fitting picks the fitting, part picks the dummy lamp, the dummy socket, the holder or the assembly and cutaway slices the assembly open. wall, clearance, holder_depth and flange_w shape the holder. gu10_socket_d, gu10_socket_h and gu10_hole_span describe the round GU10 socket puck, e14_socket_d, e14_socket_h, e27_socket_d and e27_socket_h the Edison housings. smoothness sets the facet count and color_holder the display colour of the printable part.
