Bowden Tube cutter

thingiverse

I've encountered numerous problems resulting from the bowden tube coming from the factory not being cut straight, and people generally struggling to cut it straight. To address this issue, I conducted a search and found some satisfactory solutions on this forum. However, I wanted more options, so I designed one up myself. This design utilizes a standard razor blade, which is held in place by two M2 bolts and nuts. The main arm is secured with an M3 bolt, and 8-10mm should work perfectly fine without the need for a nut. I deliberately omitted using a nut to keep things simple. To lift the blade up, I incorporated a place to use the spring from a Bic pen. Please note that this design does not have a mechanism to hold the blade down when not in use, so it's essential to keep it out of reach of small children. This design works flawlessly, and I've printed several copies already. Additionally, I added a flat base for versatility, allowing you to use it to cut various materials if needed.
