Y-Axis Bracket for Mini 3D Fabrikator Tiny Boy Final Highly Recommended

thingiverse

I had seriously reviewed a few of the designs for the Y-Axis Stepper Motor Fan Mount portion and concluded the best position for the most limited space constrained part on the Mini Fabrikator TinyBoy. Never design something that will block or hit the movement of the print while it is moving or that you're zeroing at full bed length tests! It is very obvious on larger size prints near 80mm. Heat without bracket has reached 56 to 60deg Celsius for stock printer. If your stepper reached 80deg Celsius, it would mean your POTs on Ramps Board for all steppers are not normally set to 0.60-0.62V and 1.12 at the other measured legs. Below these volts and you'll notice the extrude pauses for half a sec at certain prints resulting in multiple stains. The bracket is capable of reducing between 7 to 10deg Celsius differences as tested. Prior to the big 12cm strong fan bringing down X & Z Axis to near 34deg Celsius, putting the tiny bracket for my 30mm fan has successfully maintained the temperature to around 49deg Celsius during operation. The printer has been printing non-stop 24hours for weeks to near months without problems. I had chosen ABS Black material base (Black absorbs heat in my view) on the heat produced from the Y-Stepper but you can opt for PLA in your preferences. ABS does warp without hotbed but in my case, since it is tiny and small, I regard it negligible and acceptable as a functional excellent solution. For any equipment, as long as the operating temperature is maintained at minimal, it will be prolonged for it's lifespan. If you like the design and you would like to donate as an appreciation, you can paypal any amount to daveth26@singnet.com.sg for supporting my continual research test materials. Hope you all like it!
