The part is the strongest printed laying flat. If you have a great printer tuned-in tight print model tri_bike_number_post.stl standing up like a "T" with the slot opening up and supports under the solid part.</p> <p>My printer isn't quite good enough to do that so option 2 is to print model tri_bike_number_post_and_support.stl laying flat. This model has supports included. You'll need to trim them back out carefully. I ground the blade off an X-acto knife to a square edge to use there. This works pretty well and you end up with a really strong part.</p> <h3> Post-Printing</h3> <p><strong>Trimming supports using square ground X-acto blade</strong></p> <p><strong>Putting it all together</strong></p> <p>Uses 3mm and/or 3.5mm wide zip ties - small or medium available from your local hardware. Cleanest set up is to use 3mm white ones for attaching the number (like the small ones from GB 50098, <a href="http://amzn.com/B00004WLJ9?tag=tv-auto-20">http://amzn.com/B00004WLJ9</a>) and 3.5mm black to attach to the bike (like GB 46-308UVB, <a href="http://amzn.com/B00004WLJ4?tag=tv-auto-20">http://amzn.com/B00004WLJ4</a>).</p> <p>To use:<br/> 1\ Peel and stick the adhesive strips on your race number together to make it flat.<br/> 2\ Slip the number into the slot.<br/> 3\ Poke through the paper number where the zip tie holes are.<br/> 4A\ Use one zip tie per size and wrap it around the post. Cut off the excess.<br/> 4B\ Or... for a cleaner mount use 2 zip ties for each hole.<br/> Poke one through the hole.<br/> Thread the pointed end through the second zip tie on the other side.<br/> Cut the excess off both.<br/> You end up with the little box end of the zip ties on either side of the hole, no strap.<br/> 6\ Assemble the post into the slot on the clip.<br/> 7\ Put a zip tie through the hole in the clip to hold both together.<br/> 8\ Locate on your bike where you want it. The post is offset so flip it top-to-bottom if it fits better.<br/> 9\ Zip tie in place.<br/> 10\ Cut the excess off the zip tie.<br/> 11\ Go PR on the bike leg at your race.</p> <p><strong>Zip tie number to post, trim excess</strong></p> <p><strong>Number attached.</strong></p> <p><strong>Clip attached, ready to mount to bike</strong></p> <p><strong>Attach to seatpost</strong></p>
