Tablet holder adapter and blind cap for Ultimate Support (or Roland) V-Stand

These components fit into the horizontal tubes of the Ultimate Support or Roland V-Stand.

I am using this to attach a K&M tablet holder (the predecessor of the K&M 19744).

The V-Stand can still fold up with the blind cap in place (only if the low-profile version of the knurled nut is used). Other attachments need to be removed before folding up. Wing nuts, knurled nuts or large knobs are advisable for quick mounting and removal.

The wedge and opposite parts are held together with an M6 bolt with hexagonal head. The bolt length varies, depending on the attachments (e.g.: 60mm for the blind cap, or 90mm for the tablet holder).

The tablet holder can be attached to the adapter part with M4 bolts and nuts. It can be used facing outwards on inwards, depending on how far away you want it to be. Note that you need a mirrored part when reversing it.

Due to the angle of the stand, some parts will be different for use on the left or right side. Print mirrored where applicable.

Tablet holders typically attach to microphone stands, which use 3/8" UNC thread. UNC bolts are hard to get in my area, so I designed the tablet support adapter to also fit M10 bolts. With a thread cutter, the first part of an M10 bolt (ca 10-15mm) can be re-cut to 3/8" UNC (try to keep it straight!).

edit: I have added the FreeCAD file as well, but don't complain if it is not very useful… In hindsight, I would have done some things differently, especially the reference direction (Z is not pointing straight up, but in the direction of the V-stand leg).
