This is an improved, stylish and more convenient enclosure for the project https://github.com/lo1ol/DarkroomTimer.
6 August 2025 Update:
• Fixed the height of the bottom part of the power supply to fix a gap between the top part.
• Made bigger holes for the wires in the power supply
• Added a socket for Arduino Type-C. Now it’s possible to choose a cap between two versions of Arduino: type-c or mini-usb
• Increased the gap in the bottom part of relay body, to make it easier place on the stand
• Increased the size of the hollows for the anti-slip rubber on the stand
• Update decals
16 September 2024 Update:
• Added model of Power Switch module for 2 enlargers.
!For your safety, print it in ABS plastic because it is more fire resistant than PLA!
16 July 2024 Update:
• The timer received the official name "Red Ray Timer"!
• Little change of cap sizes for more visual balanced look
• The texts on the body have been updated
• Added localized Russian version in red
For this case you will need to purchase separately:
• 3 pcs. Low profile flat switch GATERON 2.0 or similar of the same height. With or without a click - choose to your taste (https://aliexpress.ru/item/1005005783406100.html)
• 4 pcs. M3 bolts 2cm long
• 4 pcs. M3 nuts
• 35.5x90x3mm piece of translucent black acrylic glass (like this https://aliexpress.ru/item/1005002538243937.html)
You will also need 3 bolts for attaching the toggles, 4 bolts for attaching the LCD and at least 1 bolt for attaching the Arduino. I can’t tell you their sizes because I picked them from what I had at home and forgot to measure them.
All texts and graphics are applied by UV inkjet printing or silkscreen printing on the body and buttons, a file with them is attached to the project
Parts required for power switch:
• 4 pcs. M3 bolts 2cm long
• 4 pcs. M3 nuts
• 2 pcs. BingoElec electric socket (https://aliexpress.ru/item/1005002889293694.html)
• 1 pcs. 2 position "Rocker Switch" (https://aliexpress.ru/item/32679617807.html)
All parts are designed for printing using PLA and ABS plastic with a 0.2mm nozzle and a layer thickness of 0.14mm for greater accuracy when assembling with electronic components.
I printed all the parts on a Bambulab P1S printer using PLA+, ABS+ plastic from eSUN
