I multi tooled a slot out of the front of the tub and then glued the chrono in place. It didn&#8217;t look very nice but largely did the job however changing batteries was a PITA (due to the small clearance between the battery compartment and the bottom of the tub) and it wasn&#8217;t uncommon for BB&#8217;s to bounce back.<\/p>\n\n\n\n<figure class=\"wp-block-gallery columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\"><ul

gun with a higher rate of fire and hence I started working on MK2 which should reduce the likelihood of rebounding BB&#8217;s and would also benefit from the following improvements:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Chrono mounted on lid via tripod screw and thus removable<\/li><li>Chrono to have a 3D printed muzzle cone to stop metal on metal strikes<\/li><li>Chrono to have built in rechargeable battery with vastly easier access<\/li><li>BB&#8217;s to be collected in separate area for easier removal as well as reduce BB rebounds<\/li><\/ul>\n\n\n\n<p>Unlike most of the projects I undertake, this one was fairly cheap, easy (especially if you have a holesaw and a 3D printer or have a friend who does!) and worked out exactly as intended on the first attempt!<\/p>\n\n\n\n<figure

the elbow, it doesn&#8217;t appear to have penetrated the kevlar layer underneath (silicone hoses as used in the automotive industry normally have 5-6 layers of silicone and kevlar) but in the event I do break through multiple layers in the future I will either replace the hose or figure a way to reinforce it.<\/p>\n\n\n\n<p>I hope someone finds this neat little project helpful as there
