BackBoard, cross at 90° to minimize capacitance between traces - .3mm for non-power lines, .6mm if carrying power - MK uses .6mm -- this is the cheaper option but won't reproduce tiny smooth curves all that well. MSLA (resin) printing will do far better detail work, but will need painting. Could be glued on with CA or hot glue, if the hole is a dealbreaker 7555-based "Fastest Envelope In The West" (bottom one) third iteration of a pot rotary_knob_row = top_row - 30; left_rib_x = thickness * 1; right_rib_x = width_mm - thickness*2.5 - tolerance*6; left_rib_x = thickness * 1.2; right_rib_x = width_mm - col_right; // column from edge plus hole radius h_wall(h=4, l=slider_spacing * 10 + center_adjust; right_col = width_mm - hole_dist_side, hole_dist_top); echo("Putting a hole with radius: ", hole_r , " at ", width_mm - h_margin; cv_in = [first_col, fifth_row, 0]; pwm_duty = [width_mm - h_margin - working_width/8, row_3, 0]; c_tune = [second_col, fourth_row, 0]; triangle_out = [output_column, bottom_row, 0]; cv_in = [first_col, fifth_row, 0]; //left_rib_x = thickness * 2; right_rib_x = width_mm - thickness*2; Panels/title_test.scad Normal file View File Hardware/Panel/precadsr_panel_al/precadsr_panel_al.pretty/Bigger_Push_Switch_Hole.kicad_mod Normal file View File 3D Printing/Cases/Eurorack Modular Case/DSC03778.JPG Executable file View File 3D Printing/Cases/Eurorack Modular Case/DSC03778.JPG Executable file Unescape # precadsr.sch BOM Various tweaks From cd915e24c94d463c67b0b011c09a1ed6f99bb0bf Mon Sep 17 00:00:00 2001 Subject: [PATCH 13/18] Add footprint items for panel holes; separate panel and pcb into different files Add a front-panel PCB Fireball/Fireball.kicad_prl | 2 Fireball/Fireball.kicad_pro | 104 Fireball/Fireball.kicad_sch | 64 Fireball/fp-info-cache | 23 .../SolderWirePad_1x01_Drill0.8mm.kicad_mod | 19 .../ao_tht.pretty/TO-92_Inline_Wide.kicad_mod | 36 .../ao_tht.pretty/Power_Header.kicad_mod | 75 .../precadsr-panel-MaskTop.gts | 75 .../Push_button_A-5050.kicad_mod | 13 ...6.3mm_D2.5mm_P10.16mm_Horizontal.kicad_mod | 39 ...L6.3mm_D2.5mm_P7.62mm_Horizontal.kicad_mod | 39 ...L6.3mm_D2.5mm_P7.62mm_Horizontal.kicad_mod | 39 ...L6.3mm_D2.5mm_P7.62mm_Horizontal.kicad_mod | 39 ...L6.3mm_D2.5mm_P7.62mm_Horizontal.kicad_mod | 39 .../ao_tht.pretty/Rotary_Switch.kicad_mod | 38.
