INTRO


Below you will find parts and tools, which will help you to add turn and stop signals to your bicycle. Not all tools, like multimeter or label printer, are necessary. If you noticed mistakes, have questions or suggestions, know better components (available in EU and US), please write to [email protected] • Project page: Jocys.com/bicycle

Parts were printed from PETG with Prusa3D i3 MK3 Printer. If your printer is not precise enough, printed parts may not fit into each other.

If you made your own updates or (file) changes, related to this project, please send me a link. I will add this link to your work on this page.

This project is based on 12 Volts. Bicycle dynamos and lights are, usually, 6 Volts. USB is 5 Volts. Be careful and don't mix wires.

image LUYED (China) 1157 3014 78-EX red LED bulb: Brighter than OSRAM LED bulb. All LEDs are lit in “tail only” mode. On pressing brake lever (“stop” mode), all LEDs become brighter. Difference between “tail only” and “stop” mode is minimal and not very distinguishable. You can increased difference between “tail only” and “stop” modes by dimming tail light slightly with 1 kΩ potentiometer.
image image Osram (Germany) • 1457R red LED bulb: Not as bright as LUYED LED bulb. Only 6 LEDs are lit in “tail only” mode. On pressing brake lever (“stop” mode), another 12 LEDs light up. Not as bright as LUYED bulb in both modes, but difference between “tail only” and “stop” modes is more distinguishable without dimming tail light with 1 kΩ potentiometer. Currently I prefer LUYED with 1 kΩ potentiometer setup.

image CTS Corporation • 026TB32R102B1A1 1 kΩ Potentiometer
1 x 1 kΩ potentiometer for tail light
Some LED bulbs have very small difference between “tail only” and “stop” modes. You can increase this difference by slightly dimming tail light with 1 kΩ potentiometer.

Choosing a Tool • Pressmaster
Laser • 1913 Crimping Pliers
You can crimp terminals with “C.K 495001”, but with “Laser 1913” it is much easier and faster.
For use on non-insulated terminals, the ratchet motion assures complete crimping. Forged jaws (spare jaws Part No 2927).
For use with non-insulated terminals:
0.5-1.0mm², 1.5-2.5mm², 4-6mm²
20-18AWG, 16-14AWG, 12-10AWG
Klein Tools • VDV205-036 Die Set

image Hozan • P-707
12voltplanet • P00456 (YTH-202B)
I used 0.5mm² / 20AWG / 1.7mm diameter cable. Laser 1913 Crimping Pliers (0.5-1.0mm² / 20-18AWG) did not crimp insulated part well. I used P00456 (YTH-202B) non-insulated terminal crimping tool (0.3-0.5mm² / 20-22AWG) to crimp insulation part better.

PETG FILAMENT

You will need about 1.1 kg with 80% infill
I would not recommend to print parts from ABS (shrinkage is too big) or PLA (low heat resistance).

SHLIsopropanol / Isopropyl Alcohol / IPA
NOTE: I didn't test-print parts for this project on Textured PEI Powder-coated Spring Steel Sheet.

For preparing-cleaning heated printer bed... Double-sided Textured PEI Powder-coated Spring Steel Sheet before printing with PETG filament.

For thin parts to stick correctly, you may need to adjust height of first layer perfectly and to reduce "Elephant foot compensation" from default value 0.2mm... to 0.1mm.

PRINTING SETTINGS

Printing Settings for MCPP BasicFil or AmazonBasics PETG Filament on PrusaSlicer
...for Spring Steel Sheet with Smooth Double-sided PEI

For BIG parts to stick on TEXTURED PEI Powder-coated Spring Steel Sheet sheet, I increased recommended bed temperature from 60-80°C (for AmazonBasic and MCPP BasicFill PETG filaments) to 85°C (First layer) and 90°C (Other layers). I printed BIG parts in my own Temperature Controlled Enclosure. Temperature inside enclosure was about 35°C with these bed settings. E3D V6 HotEnd is rated to 40°C ambient operating temperature. As you approach that temperature, cooling efficiency is reduced, allowing more heat up past the heatbreak. This can cause low temperature filament to soften in the mechanism to cause feed problems.

image Modified settings: PrusaSlicer ► Filament Settings ► Prusament PETG ► Filament
• "Extruder: 240°C".
• "Bed: 85°C / 90°C".
image
image Modified settings: PrusaSlicer ► Print Settings ► 0.20 QUALITY MK3 ► Layers and perimeters
• "Ensure vertical shell thickness: disabled" - I had problems with thin 45° hanging angles when it was enabled.
• "Perimeters: 6" - infill pattern is less visible on surface.
• "Seam position: Rear" - created line at the back of the parts, but front and side surfaces were perfectly smooth.
image
image Modified settings: PrusaSlicer ► Print Settings ► 0.20 QUALITY MK3 ► Inflill
• "Fill density: 80%."
image
image Modified settings: PrusaSlicer ► Print Settings ► 0.20 QUALITY MK3 ► Speed
• Reduced printing speeds (10-20-180-400). Slower speeds results in smoother and glossier surfaces without matte areas, reduces printing noise with vibrations... lesser probability for corners of big parts to unstick from heated bed, because of shrinking.
• "Travel: 180" - low speeds (like 20) creates surface blobs after long travel distances.
• "First layer speed: 10" - for better adhesion.
image
image Modified settings: PrusaSlicer ► Printer Settings ► Original Prusa i3 MK3S ► Custom G-code
• I added few lines to G-code to remove filament blob on nozzle right before printing starts and raised intro line to reduce wearing of steel sheet plate surface.

G0 Z50 ; ADDED LINE - NOZZLE BLOB - Z up 50 mm to clean filament blob from nozzle before printing.
G4 S5 ; ADDED LINE - NOZZLE BLOB - Pause 5 seconds to clean the nozzle.
G0 Z-50 ; ADDED LINE - NOZZLE BLOB - Z down 50 mm to initial position.
G0 Z0.5 ; ADDED LINE - INTRO LINE - Z up 0.5 mm for less intro line adhesion to prevent steel sheet plate surface from wearing.
G0 Y-1 ; ADDED LINE - INTRO LINE - Y shift 2 mm intro line default start position to prevent steel sheet plate surface from wearing.
