Photon-inspired resin print curing chamber

thingiverse

Been thinking of building your own UV-curing chamber? This is a project for those who are into electronics and know how to work with Arduino, like me. Don't even think about printing this if you're new to electronics - I'm not here to hold your hand through a step-by-step project. This is for people who already have the basics down and just need something to put their gear in. I've included a STEP-file of the top if you want to adapt it for other displays and/or buttons. It's a DIY-project where I used leftover components, so I won't offer a circuit diagram here - you should use your own components, not mine. If I were buying components for this, I'd get an Arduino nano or similar, a dual-channel motor controller board to control the LED-strip and the rotation motor. The board should be able to handle at least 1,5A because the LED-strip (at least the one I have) uses a bit over 1A continuously on 100% duty. In mine, I used some left-over MOSFET's, a 5V regulator that keeps getting too hot, so will need to replace that, and I used a NodeMCU (ESP8266) which is way overkill for this, but I had a bunch of boards laying around. The annoying thing is that NodeMCU can just handle up to 10V so I couldn't power it directly on my 12V power supply, which is why I'm using an external 5V regulator. However, I developed the code in the Arduino IDE, so you can re-use my code if you're using any Arduino-board - just make sure to change the pins to the ones you're using. You might also need to change display library to whatever display you choose. Display I used: Luxorparts 1,3" OLED https://www.kjell.com/se/produkter/el-verktyg/elektronik/optokomponenter/led-lcd-displayer/luxorparts-oled-display-for-arduino-13-p87946 Button: 5-way tactile joystick from a scrapped computer monitor. Even though the board I've used is not available for purchase, if you search for "5-way tactile" you will find the component and there are multiple breakout boards - or you could replace it with just a button to start the curing process. UV-LED strip: https://www.ebay.com/itm/UV-Ultraviolet-Black-Lights-LED-Strip-300-LEDs-16-4Ft-5M-3528-Flexible/192926297864 Motor: 12mm DC-motor with planetary gearbox. Mine are not available for sale online from what I can find, but if you search for "12mm DC-motor with planetary gearbox" there are many available variants - also try to choose a motor with a winding already for 12V so you won't run in to the issues I have with a too fast motor. Ballbearings: OD=15mm ID=10mm T=4mm https://www.ebay.com/sch/i.html?_from=R40&_trksid=m570.l1313&_nkw=ballbearing+15x10x4&_sacat=0 Door is kept shut using round magnets, 4mm long and 4mm diameter. For hinges I used M3 nylon screws mounted on the top and bottom of the door and with their heads cut off so that roughly 3mm sticks out from the door - that works well as a hinge mechanism. Screws needed are M2 and M3. I mounted the LED strip on a pre-cut piece of paper that was then glued in place. Almost the entire LED strip fit in the box, so roughly 300 LED's. A few words about the parts: Foot-print: 4pcs, preferably in TPU or other flex Platform-bearing-plug: you need 3pcs of these for the ball bearings that supports the rotating platform Chamber: This massive piece can be printed without support! There will be a few sagging lines here and there but it worked beyond expectation to print without any support.
