<p>Update 11/17/19: New files uploaded, 7-8_3-4_short_insert. Meant for 7/8"x3/4" orings to allow a thicker wall between the oring and the barrel for easier printing. For the more metric-minded, it'll fit an oring down to around 19mm ID, 22mm is probs what OD you'd be looking for. Also, hit me up if you want one sized for a specific oring or barrel.</p> <p>Update 11/15/19 preview: I recommend waiting to print the oring portion until I get this update up. I'm moving to 7/8"x3/4" orings in an attempt to get more than a single wall on portions of the inner piece to help it print better on .4mm and up nozzles.</p> <p>Update 10/30/19: Now includes a piece to help center your dart barrel into the front of the Knockout barrel to keep it nice and straight. A bit of tape wrapped around the piece and it should be a nice firm fit into the front. Slightly conical to account for printing tolerances.</p> <p>Want an easy way to fit a dart barrel into a Rival blaster? Here you go. Made to fit 16mm OD barrels and use #13 orings, which are 7/8"ODx11/16"IDx3/32". You can use a thinner oring but a thicker one in my experience makes the print split. Just stick this onto your barrel and it's a nice snug, mostly airtight fit.</p> <p>In line with my preferred way to work, this is completely uninvasive to the blaster used as well as entirely reversible. Works especially well for the Knockout where it already has a functioning breech that benefits from as little as just a barrel shoved into it.</p> <p>I'll probably make a front alignment cone piece that butts up into the wider part of the Rival barrels just to help align the barrel farther out from this piece.</p> Category: Toys & Games
