Trombone + Tablet stand

For each rehearsel I had to carry both my tablet stand and trombone stand with me, which was quite cumbersome, so I designed this holder to combine both stands into one.

Design is created for K&M stands 

Parameters:
- Tablet stand tube 17.00 mm
- Trombone stand tube 16.40 mm
- Tablet stand bottom tube 20.00 mm
- Model dimensions 24.00 X 170.00 X 235.00mm
- Basstrombone bell size roughly 280 mm (most trombone should fit)

Printing:
The model was designed with the intention to be printed without supports, as the biggest overhang is only 45 degrees. Print it in the orientation where to two holes are on the print bed.

Assembling:
There are two options one with a hole to add a heat insert and one without, this is meant to lock the trombone stand in place. The hole is roughly 4,30 mm in which you can insert a M3x4x5 heat insert.
 

1. Take of the top part of your tablet stand, this can take quite an amount of force due to the ribs you can see in the picture.
2. Allign the model over tablet stand hole, insert the top of the tablet stand and push inside the bottom part of the tablet stand.
3. Secure the model with two t-raps (cut-outs are implemented in the model)
4. (Optional) Add a M3 bolt with a printed handle. Design from RemiRafael was used in the pictures: https://www.printables.com/model/359479-handles-for-m3-to-m6-bolts-and-screws
