Hand Held Foam Cutter

thingiverse

This is my hand held battery operated foam cutter i made to sculpt my terrain pieces. the handle is designed to hold 2 pieces of M6 threaded rod that are bent is shape. using 4 nuts and 4 washers you can attach a length of nichrome wire. I used 28Ga since that is what i had. In the handle there is room to connect wires to each piece of M6 rod for power. The handle is held together by 4 M4x20mm bolts and nuts. The box is just an empty box that holds some li-ion batteries, a balance/charge board and a dc pwm speed controller. It has holes for the knob of a pwm board. a dc jack for charging and a aviation plug for he cutter itself. I just hot glued the lid and the stuff in the powerbox to the power box as i was too lazy and in a hurry to get to sculpting my foam to add screw holes. My battery is 3 18650 cells in series. some links to the components i used [Battery controller](https://nl.aliexpress.com/item/4000354337413.html?spm=a2g0o.productlist.0.0.19c07782oZc5UD&algo_pvid=9f127715-c1f1-46b4-a403-a860b69d5897&algo_expid=9f127715-c1f1-46b4-a403-a860b69d5897-25&btsid=0be3743b15885864231235460efc9d&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_) [Nichrome wire](https://nl.aliexpress.com/item/32799524515.html?spm=a2g0o.productlist.0.0.63861bb6lSmoPz&algo_pvid=3fd566dd-f79e-4fc6-a13c-ac7b7cce8e4b&algo_expid=3fd566dd-f79e-4fc6-a13c-ac7b7cce8e4b-0&btsid=0be3743b15885866522581978efc9d&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_) [PWM speed controller](https://nl.aliexpress.com/item/32945688578.html?spm=a2g0o.productlist.0.0.5f751498YZ6DwM&algo_pvid=bdcd2b13-0d02-4e20-970a-bb5a48d70e21&algo_expid=bdcd2b13-0d02-4e20-970a-bb5a48d70e21-2&btsid=0be3743b15885867232163745efc9d&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_) [DC Jack and plug](https://nl.aliexpress.com/item/32837700581.html?spm=a2g0o.productlist.0.0.721d7762fvL2AA&algo_pvid=847a0cf7-24b4-41c0-b18f-b0d643975dd9&algo_expid=847a0cf7-24b4-41c0-b18f-b0d643975dd9-23&btsid=0be3743b15885867731585322efc9d&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_)
