Hollow Knight

<html><head></head><body><h3 class="thing-component-header summary summary">Summary</h3>
<div><p>I found a few ok 3d printed designs for bolts but they were a little thin and a little light and would not work on a Viper SS as they were too thin to turn off the anti-dryfire safety. Others worked but were too heavy.</p>
<p>My design attempts to fix both of these problems. It has a solid front but a hollow rear. This allows for a front heavy bolt and counters the added weight of the fletching.</p>
<p>Suitably strong and they fly nice. They also work with the cobra style pistol crossbows as well.</p>
<p>Print with 100% infill.<br>
Supports only touching build plate. Otherwise you are going to have a fun time trying to clean out that small hollow in the bolt.</p></div>

Viper SS, Redback, Cobra Pistol Crossbow bolt

I found a few ok 3d printed designs for bolts but they were a little thin and a little light and would not work on a Viper SS as they were too thin to turn off the anti-dryfire safety. Others worked but were too heavy.

My design attempts to fix both of these problems. It has a solid front but a hollow rear. This allows for a front heavy bolt and counters the added weight of the fletching.

Suitably strong and they fly nice. They also work with the cobra style pistol crossbows as well.

Print with 100% infill.
Supports only touching build plate. Otherwise you are going to have a fun time trying to clean out that small hollow in the bolt.

<p>These are hollow &quot;Peg Links&quot; that interconnect, to allow the wire to pass up the middle. Print 1 fan top and one base, then as many &quot;Plinks&quot; as needed, pass the wire through the hole in the fan top, before connection the fan, then through each link, before snapping them together...<br>V1.11 - fit is a little more snug, also mount tabs are wider, and added a new bottom tab mount...<br>V1.12 - Fan Mount Break Off Tabs needed rafts</p>
