A fork support is inserted in between the fork of a bike to help hold the suspension rigid during transportation the bike.

If the suspension is not held rigid during transportation, it will be constantly activated due to the vibrations from the vehicle. This leads to early failure of the suspension. To prevent any damage and provide a longer life of the suspension, a support is inserted so that the suspension can no longer be active during transportation.

Cost savings

• If your solution is not a low cost one then it is not really appropriate.

1. Total mass of parts = 0.066 kg; Cost of spool of PLA = $26.45/1 kg; Total cost to fabricate parts: $1.75
2. Commercial equivalent cost: $14.99; http://www.motorcycle-superstore.com/48559/i/bikemaster-fork-support-for-tiedowns?SITEID=Google+SEARCH+NON-BRAND+Product+Level+Ads+-+Google+Shopping+Campaign&P_ID=1327457057&adpos=1o4&creative=93111299933&device=c&matchtype=&network=s&gclid=Cj0KEQiApqTCBRC-977Hi9Ov8pkBEiQA5B_ipS2TNlLoZ-8zdUu_BksAUxd_f7rGUYU9OFqNjXyuwxAaApXe8P8HAQ
