Robust Adjustable Tilt Tablet Stand
by inhale3d, published
Beefy, adjustable tilt tablet stand. Designed in ViaCAD.
Inspired by Thing: http://www.thingiverse.com/thing:31831
I printed and used http://www.thingiverse.com/thing:31831 and thought it was a great design - really fun to put together and looked great. The main downside was its small size and narrow stance - therefore it had stability issues for Kindle and larger tablets. Worked fine for iphone and was marginal for an iPad mini.
So, I decided to start from scratch in ViaCAD and designed an adjustable stand tipping my hat to Thing 31831 and looking at my Chaise Lounge tilt design. This stand is improved in these ways:
1) Overall larger scale and beefier structure
2) Much wider stance for more stable tablet cradle
3) Easy to print
4) No long screws are needed. Many fewer fasteners required.
5) Easy hardware requirements - only 4 M5 x 0.8 x 16mm socket head bolts and 4 M5 x .8 nuts are used (black socket head bolts look cool.)
6) Provided ViaCAD source files for your tinkering pleasure (any of the .vc3 files are the source files)
7) Cradle is deeper to accommodate tablets without removing their cases
3D Print the 3 STL files:
Base: tablet-stand-base.stl [updated 12/15/12 to open nut cutouts to make it somewhat easier to press in M5 nuts. Updated 1/8/12 to beef up spars in base so there is less flex. replaced stl and vc3 files for base]
For the braces and uprights, there is a left and a right part included in the STL.
I used a LulzBot AO-100 for the print, 0.5mm nozzle, 0.3mm layer height, 1 vertical shell. The Slic3r INI file I used for the test print can be downloaded at the left - filename: Inhale3D-tablet-stand.ini. That'll give you a head start on a print config.
Assemble the stand as shown using 4 M5x16mm bolts and nuts. The nuts press in to the base and braces from the inside joints. It's easiest to use either channel lock pliers or vice-grips adjusted with a wide jaw - need wide jaws to squeeze it into place so it's flat. The nuts are a very tight fit and can't easily be pressed in by hand, but this makes for very solid-feeling joints.
(ViaCAD 2D3D 8 for design, Strata Design 3D SE used for raytraced renderings shown, LulzBot AO-100 for test prints, Slic3r 0.9.7 for gcode.)
