I have a lot of Ultralux LLVP1242 downlights at home. Every month I have to replace at least one or two of them, and it's gotten quite expensive (at 12-15 euro each), so I decided to convert them to regular GU10 LED bulbs.

This model allows you to mount GU10 bulbs instead of the factory LED module that is so overpowered that it burns out so quickly.

All you need is:

- a cheap GU10 socket (ceramic or whatever)
- a GU10 bulb you like (I used some 1000lm 4000K bulbs)
- Some glue (preferably one that won't melt, since some of these bulbs get pretty hot)

Use heat-resistant material for printing, such as ABS.

Now anytime I need to change the bulb it costs me 1-2 euros for the bulb instead of 12-15 for the whole lamp.

LED Downlight Adapter to GU10 (Ultralux LLVP1242) 

This 3D model is a test tube rack that I made for a genetic laboratory. It is designed to hold test tubes of two different sizes - approximately 18mm (30pcs) and 31mm (20pcs) in diameter. The rack is lightweight, durable, and can be used repeatedly.

The precision-molded slots of the rack ensure a secure fit for your test tubes, preventing spills and breakages. Its compact size makes it easy to store and transport, while its sleek design adds a modern touch to any laboratory.

If you work in a laboratory or conduct scientific experiments, this test tube rack can help you keep your test tubes organized and easily accessible. Simply 3D print the model using your preferred material, and you'll have a useful tool to streamline your laboratory workflow.

The design is not perfect and can definitely be improved, but it does its job well. Maybe some day I will find the time to improve it.

Cyanoacrylate can be used to secure the two pieces together, or you could also use melted filament.
