Big LED Arch with only 3 different parts to print.

No support needed, just use brim for the Arch.

You need to print:

• 14x Arch.stl,
• 1x Base1.stl or Base1_touch.stl and
• 1x Base2.stl.

Each base have cutouts for 7 x M12 nuts (the Touch-Version 8x), to add weight (about 100g per side). It's not needed, but could add stability. To insert the nuts you must stop the print after 10.7mm layer! (M600 - Filament change)

The switch hole on Base1 is 13x20mm (you can ad a support there, but is not needed). Matching switches: 2 way rocker On-Off, 3 way rocker On-Off-On

On the Arch there fits two 10mm LED Strips side by side with a length of 230cm. (100cm 71er Arch)

Size assembled: Width: 154cm Height: 81cm

If you want to use the 3 way rocker: You can solder the + from stripe one to "I", the + from stripe two to "II", the power on the center of the switch and a diode (1n4007) between I and II. If switch position "I",one stripe lights up,and if switch position "II" both stripes lights up.

Update: 30.08.2019 I add a Version with a Brightness Control - Touch Sensor Switch Module and a 5,5/2,1mm DC Mount. https://www.ebay.de/itm/175067499202

Update: 23.03.2023 On request I created a diffuser, so I add two Diffuser (Round and Flat)

Update: 20.02.2024 (untested) On request I add a arch piece for width 71cm, print it seven times for a semicircle.  The bases should work, shorten the stub of the Base1 and the last arch piece connected to Base2 slightly.
