Update:
I redesigned footrest support, now base can be smoothly adjusted in the range of 5 cm.
POM:
screws: 2pcs M4 hex head 35mm, 2pcs m4 flanged button (or round head) 30mm
nuts: 2 pcs m4 hex nut, 2pcs m4 nylock nut
Support elements have to be printed in two instances - one mirrored, 3 walls, 15% infill. Lay flat with supports
Old version:
Simple footrest for IKEA's child highchair BLAMES. Footrest can be set in 3 different hights. Easy fitting - can be fixed with doubleside adhesive tape or screw.
Printed from PETG, but you can use PLA as well.
You have to print footrest support in two instances - one have to be mirrored.
Print it with highest layer, footrest support print flat, 3 walls, 3top/bottom layers, 15% infill, triangles,
Footrest can be scaled if to long - original model has 25cm, fits well in print height of many 3d printers (compatible with both support versions). Print footrest with 2walls, 3 top/bottom layers, 15% infill
The author marked this model as their own original creation.
