Laser Bong

Tired of using lighters? Want a bong that can burn your retinas? Me too!!!! BUY SAFETY GLASSES THAT MATCH THE WAVELENGTH OF YOUR LASER. THIS IS A CLASS IV LASER, YOU CAN AND WILL BLIND YOURSELF OTHERWISE. The laser is a 7.5 watt laser module easily found online (ex. https://www.aliexpress.com/item/1005003151908792.html) Three 18650 Lithium batteries give a high enough voltage, I used the three cell case found here (https://www.thingiverse.com/thing:2339441) These switches should work (https://www.aliexpress.com/item/1005002007849345.html?spm=a2g0o.productlist.0.0.2aca3b57pIAtjz&algo_pvid=c481bddf-d80d-4a0b-aa41-50270c4cbca2&algo_exp_id=c481bddf-d80d-4a0b-aa41-50270c4cbca2-7&pdp_ext_f=%7B%22sku_id%22%3A%2212000028067008772%22%7D&pdp_npi=2%40dis%21CAD%21%210.71%21%21%213.18%21%21%402103250d16577334654986545e187e%2112000028067008772%21sea)(https://www.aliexpress.com/item/1005002007849345.html?spm=a2g0o.productlist.0.0.2aca3b57pIAtjz&algo_pvid=c481bddf-d80d-4a0b-aa41-50270c4cbca2&algo_exp_id=c481bddf-d80d-4a0b-aa41-50270c4cbca2-7&pdp_ext_f=%7B%22sku_id%22%3A%2212000028067008772%22%7D&pdp_npi=2%40dis%21CAD%21%210.71%21%21%213.18%21%21%402103250d16577334654986545e187e%2112000028067008772%21sea) SORRY TOO LAZY TO USE TINYURL This Project was designed for a bong with a diameter of around 50mm. If your bong is a different size and you need help modeling, just ask in the comments! The bolts used are simply M4 bolts. Case and bong mount may be printed separate if desired. If "laser bong body" is chosen be sure to use tree supports. Wiring is very straightforward. Red (positive) and Yellow (PWM) can each receive 12v, black (negative) simply goes to the negative wire coming off the battery case. Both buttons are wired in series between the battery and 12v input wires (yellow and red). Battery case must be glued inside bong case. Only glue battery case into laser bong case after wiring. Bong mount must be heated to bend around the bong, simply use a heat gun, hairdryer, or torch to carefully heat the side opposite the bolts. I put a few rubber bands in between the glass and the mount to minimize slipping. Tips for using -ALWAYS turn safety switch on when not in use -Rotate bowl as laser is on to spread cherry -Pack greens down hard so cherry spreads better -Focus the laser slightly past the focal point so the area being hit is larger That's it! Be careful and get smoking!
