Small shelf for putting on top of shower mixer taps to create a more stable surface to keep shampoo, shower gels etc.

The shelf simply sits loosely on sections of the supply pipes in the back, and rests on the top of mixer tap in the front. 

Sizing/scaling:

Depending on the specific model and brand of mixer tap, you might need to scale it a little.

The distance between the supply pipes should pretty much be standard(worldwide?) at 150mm leaving the width fixed.

You probably need to adjust the scale of the depth and height however. By default it fits a mixer tap with 15mm from the top of the water supply pipe fittings to the top of the mixer tap. And roughly 60mm horizontally from the resting point on the water pipes to the middle of the mixer tap. Non-uniformly scale the depth and height accordingly.

However, there is a lot of variability on shape and design of mixer taps, as well as differences in plumbing and cosmetic details where it connects to the pipes/wall. So I cannot guarantee it works for all. I have included a STEP-file so you can try and adapt it to your specific situation.

Printing:

Nothing fancy required. Either print it solid or maybe increase perimeters, top and bottom layers a bit to make it slightly more waterproof.

I printed mine with:

Layer height: 0.15mm

Perimeters: 3

Top and bottom layers: 7

If you live in an area with a lot of lime in the water and get a lot of limescale deposits, keep in mind that PLA is not very acid resistant. So if you use a lot of descaling products, it might degrade faster. PETG and ABS-like filament should be slightly more resistant.
